1 INTRODUCTION 1.1 OBJECT

This General Specification (GS) covers the detailed requirements for the UMTS Dual Duplexer and low noise amplifier (DDM) that is developed by a subcontractor.

1.2 SCOPE

The UMTS DDM defined in this document is for use in an outdoor and indoor Cellular Base Station product. Hence, it must conform to all normal regulatory and industrial-based standards and guidelines. The Duplexer component of the module provides two functions:

� Isolation among the transmit signals and receive signals thus facilitating the use of one antenna per diversity branch per sector.

� Filtering of transmit and receive signals thus reducing interfering signals. The LNA provides low noise amplification at the system front end thus reducing the overall effects of noise. After the LNA, the receive band signals are split into 3 local outputs prior to distribution, via coaxial cables, to the transceiver shelves. In addition, a VSWR monitor circuit is provided to monitor forward and reflected power at the antenna port. It supervises then the connection between the BTS and the antenna. The DDM will interface with the TRM processor via the I²C interface. LNA consumption alarms and VSWR monitor fault alarms will be monitored through an addressable I/O port expander. Calibration, manufacture and performance data will be stored and accessed through an addressable EEPROM.

5 GENERAL DESCRIPTION 5.1 GENERAL PRODUCT ARCHITECTURE

DDM operates within UMTS base station equipment frames. DDM is the last stage in the transmit section of the FRM after the MCPA and preceding the antenna and lightning surge protectors.

In the receive section, DDM is the first stage of the FRM following the antenna and lightning surge protectors.

The DDM is intended to operate in the following paired band: � 1920 – 1980 MHz: up-link � 2110 – 2170 MHz: downlink.

System design permits an easy transition from receive diversity to transmit diversity signal, and this up to four carriers per sector.

Following figures describe overviews for STSR configuration with 2 carriers BTS configuration. DDM enables 2 single antennas (Main and Div) to be used for up link and down link. In order to provide an antenna Rx diversity signal, one Diplexer/LNA and a Rx filter/LNA only are required (configuration 1). This means that DDM is not fully used. In complete diversity system, two Diplexer/LNA sets are required (configuration 2).

Figure 2 : DDM System Overview : STSR – 2D carriers Moreover, TMA can be installed close to the antenna in order to improve sensibility. This module is an external equipment. This ancillary includes a receiver amplifier which has to be DC supplied and alarm monitored. DDM has to support these functions only in the case of UMTS TMA single band is used. This excludes any other type of TMA (dual or tri bands…). See R3.

(1) Cf Appendix 1 for more details about the IMD level calculation at the ANT port. (2) A blocking level at +16dBm in the (2010-2025) MHz allows BS FDD-TDD co-location.

7.3.2 BLOCKING REQUIREMENTS

The following tests permit to define both RX input filter and inter-stage filter masks. The 25.104 specify a blocking level outside the RX UMTS band at –15dBm (BTS input). When GSM 900, DCS 1800 and UTRA FDD BS are co-located this level increases at +16dBm in the (925-960) MHz. When UTRA-TDD and UTRA FDD BS are co-located, the current state-of-art technology does not allow a single generic solution for the same 30 dB BS-BS coupling loss used to calculate the requirements for GSM and DCS co-location:

⇒ (1900-1920) MHz TDD band: the blocking level is defined at -40dBm (co-location not technically feasible).

In this case, certain site-engineering solutions can be used, these techniques are addressed in a TR referenced in the 25.104 document.

⇒ (2010-2025) MHz TDD band: blocking level at +16dBm, which allows BS TDD – BS FDD co-location The blocking level inside the UMTS RX band at the BTS input is -40dBm.

3. VSWR at antenna port up to 1.4:1. There shall be no isolation degradation when antenna port VSWR is 1.4:1.

4. Applicable between the main transmit port and main receive ports of the Duplexer Main within the transmit pass band frequencies. Gain is defined as the gain between the main antenna port and the main receive ports.

5. Applicable between the main transmit port and main receive ports of the Duplexer Main within the receive pass band frequencies. Gain is defined as the gain between the main antenna port and the main receive ports.

6. Applicable between the main transmit port and diversity receive ports of the Duplexer Main within the receive pass band frequencies. Gain is defined as the gain between the main antenna port and the diversity receive ports.

7. Maximum insertion loss includes internal bias Tee.

7.5 VSWR MONITOR

Two VSWR monitors are included within DDM. The aim is to be able to monitor RF mismatching between antenna and BTS. This means that information coming from DDM would allow to supervise connections and cables degradation only but in any case this can not be compared to lab tool.

The reverse path of VSWR monitor have to be protected against any interferer signal coming from air antennas except UMTS co-sitted carriers in order to avoid alarms not due to a false VSWR . In this way OEM Supplier has to provide a suffisant rejection of any GSM, DCS or TDD signals present at Ant port with a maximum level of +17 dBm.

In the case where external equipment such as tri-plexer module or whatever, would be installed close to the BTS, VSWR monitor would lose a lot of part of its advantage. Indeed, the supervised matching would be reduced to cabling between BTS and external equipment only.

VSWR monitor receives from dedicated RF couplers two signals proportional to the forward and the reverse power levels. These couplers are located internally, between DDM antenna port and Filters. Two twice couplers are required for main and diversity parts. The forward and reflected powers are measured; the matching is deduced and compared to three fixed values. VSWR monitor shall provide four logical signals corresponding to the four positions of the VSWR monitor value compared with the three threshold values.

IDLE MODE: BTS stops to transmit during one slot (= 666µs = 1/15 trames) each 75 slots to allow the MS to make interference measurements. During this slot, TX input level is 20 to 30 dB below its max TX power. Idle mode must be transparent for RF detection and VSWR measurement (RC of the filter enough to avoid such modulation).

Note: 0: logical low 1: logical high The thresholds are calibrated using a set of calibrated loads and at the center pass band of the DDM.

VSWR measurement uncertainty shall be lower than:

� VSWR 1.5:1 threshold: ± 2.5 dB

� VSWR 2:1 threshold: ± 1.9 dB

� VSWR 3:1 threshold ± 1.6 dB

If VSWR Monitor Tx power input is below 23dBm (-3dB/+0dB) , the logical alarm signals will be [0 0] (VSWR_threshold1 and VSWR_threshold2).

VSWR Monitor response time shall be better than 1 second. Specific cares have to be took regarding false alarm – see [A1] document. Design has to be approved by ALU.

7.6 SUPPLY VOLTAGE & DC INTERFACE

DDM shall include one or two DC/DC converters supplied by -48V voltage. Supplier has only to prove and meet MTBF target with the chosed solution.

7.6.1 -48V DC INPUT VOLTAGE RANGE SPECIFICATION:

The nominal power supply voltage is inside the range –36 V to –60V with no damage range covering 0 to –36 V & -60 to -75.0 V.

7.6.2 DC/DC PROTECTION:

To protect DDM against bad running, the DDM must contain an internal electrical or mechanical power fuse of 1A on DC input (primary only at least).

7.6.2.1 INRUSH CURRENT

An inrush current limiter circuit must be sized to support a current surge of 5A max (hot plug manipulation). Sub-D connector (and all concerned components) shall sustain this current surge without damage. The supplier has to verify that this value meets the requirement of the power converters safety approval (this fuse requirement is also captured in DDM specification - Product Safety). The test bench is defined as following:

� The DC power source has no current limitation (capacitors must be added to supply the necessary peak surge). It is required to add capacitors close

Page 25: DDM-3 Specifications V01.05

UMTS 2100 DDM-3 Technical Specification

UMT/BTS/DD/016933 V01.05/EN Standard 09/02/2007 Page 25/84

to the DC connector of the test bench equivalent to ten to one hundred times the value of the capacitors at the –48V DDM input.

� The inductor source, including the test bench wiring, must be between 0.05 and 0.1 µH.

� The resistance source, including the test bench wiring, must be between 0.05 and 0.1 Ohms.

� The worst case is obviously by applying to the DDM a "Dirac" or square wave input DC voltage. So, to ensure this, it is mandatory to use either a mercury switch or a MOSFET circuit to strongly apply the 55V DC source voltage to the DDM.

� Between two measurements, it is mandatory to ensure that the inrush current limiter circuit is fully discharged and operational.

� Between 2 measurements, it is mandatory to ensure a complete discharge of the DDM input capacitors.

The measurement configuration is defined as following:

� The DC voltage source must be adjusted to -55V.

� The input DC current must be measured with an insulated high BW current probe (at least 1Mhz) at the –48V_IN Sub-D connector pin.

� The input DC voltage must be measured concurrently with the input current.

The Tests of inrush current is defined as following:

All the measurements may be only performed at ambient temperature of 25/35°C and with the RF input applied. This test mu st be done only to be sure that the peak surge current due to the LNAs should not be more than the inrush current mask.

7.6.2.2 TMA DC INTERFACE

TMA can be remotely DC feed through DDM T-bias. This means that DDM shall monitor current consumption. In the case where fault is detected (out of nominal range – it can be short circuit for example), DDM shall protect itself by limiting current consumption. This can be done through waste load or/and DC/DC converter voltage control for example. In any case, DC supply doesn’t have to be switched off automatically.

The aim is as soon as failure disappears (TMA is changed for example), DC supply comes back to nominal value and no DDM reset is mandatory to recover initial conditions.

Parameters Specification

Nominal Voltage range (+11 to +15) VDC

Maximum current consumption (operating mode) within 0 to 15 V DC range 120 mA

Minimum current consumption limitation 220 mA

Surge current (*) 10 mC

Maximum peak power duration 0.4 ms

7.7 LIGHTNING PROTECTION

No quarter wave or gas tube is required within DDM. This function is provided through an external RF cable linking BTS faceplate and DDM. But residual voltage appears after such protection. So dedicated protection (one device per main and diversity branch) within DDM is mandatory.

The serial data and clock lines on I²C bus are differentially driven, unidirectional serial lines. The I²C bus architecture is shown in Figure 7. Two I2C ports expanders are used : one is dedicated to writing operations (Write Protection of the EEPROM, switch command) and the second is dedicated to reading operations (alarm and presence reports). The difference between the 2 addresses is given by A0.

RS-485 Requirements : The differential line driver shall fulfill RS485 requirements (Linear Tech LTC1688 or the equivalent). By default, the driver I2C must be in three-state outputs and maintain “0” during transmission to the TRM or High Impedance in three-state. The reason is to avoid any conflict when the I2C (DDM – TRM) bus is shared between 3 DDMs. Additionally, a generic footprint approach for the RS-485 iBTS interfaces is recommended. It guarantees that we get the artwork right. All of the following elements (cf figures 8 and 9 below) on the receiver and driver parts may be needed and placing appropriate footprints guarantees we need no further artwork cycles.

Figure 9 : I²C Bus Architecture : Receiver part Notes on the figures 8 and 9: The footprints in blue in the design (except Transzorbs) must be equipped with Zero Ohm resistors on the board, as they are shorts across places where future components may be added. The other footprints are not equipped today. Note on the implementing footprints for further serial interface evolutions: - AC parallel terminations on driver and receiver are required as they are all stubs in a multi-drop network and to reduce DC current draw. - Failsafe pull up / pulls down resistors are for tristate bus definition (guarantee > 200mV and Thevenin impedance matching the cable (100-120 ohms)). Note on ESD Diodes: RS-485 requirements include ESD compliance inherent in device, plus external transzorb protection. SM712 TVS diode (or equivalent) is used to provide ESD protection to 15kV (air) and 8kV (contact) per IEC 61000-4-2.

differential lines and ground, should be high impedance for voltage between –7V and +12V and shunt transients outside this range to ground. In practise, the ESD diode has to be designed for a maximum protection that matches the characteristics of common mode voltage of its receiver. The minimum protection level is defined by both the TRM receiver main/safe terminations and the DDM driver 's power supply. The Digital ground on the dTRM is linked to the FGND of the DDM so ground loops between the transmitter and the receiver will result in very small voltages at the receiver which never exceed the receiver 's power supply lines. ESD diodes, which match the far end receiver, should also be placed at transmitter outputs.

TRM software is able to detect, via a cable detect line (CABLE-DETECT), if a DDM is physically connected at its interface. On the DDM side, pin 13 and pin 14 of the 15-pin Dsub connector are connected together.

7.9.2 I²C EEPROM ADDRESS

Up to 3 DDM can be connected on the same bus. This means that DDM interface has to be tri state. The system has three device EEPROMs (one EEPROM per DDM) on I²C bus. The address of each EEPROM corresponds to a specific position of the corresponding DDM in the BTS. These three addresses are defined by the state of A1 and A2 EEPROM inputs. +Vcc (+5 V) shall be protected by a diode. Moreover, I²C interface has to be compatible with 5 V DC supply coming from Pin 12 (Vcc input). This leads to components modifications such as regulator, receiver and driver. Figure 6 describes the electrical configuration to detect the presence and the physical address of the DDM in the BTS.

7.9.3 SOFTWARE

7.9.3.1 LNA MONITORING

The LNA monitoring shall indicate the health of the main LNA and diversity LNA. LNA_main_fault and LNA_div_fault signals input to P0 and P1 of the I²C port expander are the LNA fault alarms for the main and diversity LNAs respectively. The alarm logic is:

• 0 (logical low) indicates LNA normal operation. • 1 (logical high) indicates LNA fault.

When the LNA is not powered (no DC power) the logical signals should also indicate an alarm.

ALU (Alcatel-Lucent ) has to approve alarm circuitry design.

7.9.3.2 VSWR MONITORING

As for the LNA software paragraph (6.6.3.1), the VSWR monitor monitoring shall indicate the health of the main and diversity VSWR monitor. VSWR_fault signal input to P2 of the I²C port expander is the VSWR current consumption alarm for both main and diversity VSWR monitors.

VSWR_threshold1_main, VSWR_threshold2_main, VSWR_threshold1_div and VSWR_threshold2_div signals input to P3, P4, P5 and P6 of the I²C port expander are the VSWR monitor threshold alarms for the main and diversity VSWR monitors.

VSWR_presence signal input to P7 of the I²C port expander is the detection signal of the presence of the VSWR monitor in the DDM module. VSWR_RF_main and VSWR_RF_div signals input to P10 and P11 of the I²C port expander are the detection signals of an RF signal at the output of the VSWR monitor. The VSWR monitor shall provide an alarm if the RF signal at the output of the coupler is out of the total Tx band power range: 23dBm to 47dBm. The alarm logic is:

• 0 (logical low) indicates VSWR monitor normal operation. • 1 (logical high) indicates VSWR monitor fault.

When the VSWR monitor is not powered (no DC power) the logical signals should also indicate an alarm.

ALU is to approve alarm circuitry design.

When the DDM feeds a double UMTS TMA, it shall control the current consumption and raise an alarm if the current is out of a defined working window (thresholds). A ‘0’ indicates normal operation. A ‘1’ indicates failure. This means that TMA fault is not monitored when TMA mode is not selected.

7.9.4.3 VSWR MONITORING

4 LEDs are required: one orange and one red for Main and Div path.

The VSWR DDM monitor at the following conditions activates the LEDs:

Table 16 : VSWR LED function

When the TX Diversity is not implemented, the 2 Diversity LEDs are not activated (OFF). The VSWR LEDs alarm status of VSWR > 3:1 will be memorized as long as there is no RF input power detected or there is no reset of the LEDs alarms. The reset is generated by 2 ways:

- Power cut of the –48V DC supply - TRM software reset command sent to P03 port of the writing I2C port

expander. Per default, the P03 port state is 1 (logical high). VSWR LEDs uP will manage the LEDs reset on interruption mode at high to low transition corresponding to a TRM I2C reset command. TRM software writes a ‘1’ state on P03 port after a reset command to enable VSWR uP to manage another reset.

7.9.5 FIRMWARE

The manufacture, calibration and performance data is accessed through an I²C EEPROM within four table formats stored in the EEPROM memory. DDM unit memory location is as follows: EEPROM configuration data

The first table starts at byte 0 to byte 88 (Table 13: EEPROM Configuration Format). DDM Main receive Parameter Data

The configuration data describes hardware module specific information. The main receive parameters denote relevant receive measurements (Gain, NF, Input IP3 and Delay) from main antenna port (Main Ant) to main receive output port (Main Rx1, Main Rx2, Main Rx3 and Main Rx4). The second table starts at byte 89 to byte 143 (Table 14: EEPROM Receive Data Format). DDM Diversity receive Parameter Data

The diversity receive parameters denote relevant receive measurements (Gain, NF, Input IP3 and Delay) from div antenna port (Div Ant) to div receive output port (Div Rx1, Div Rx2, Div Rx3 and Div Rx4). The third table starts at byte 144 to byte 198 (Table 14: EEPROM Receive Data Format). DDM Main Transmit Parameter Data

The main transmit parameters denote relevant transmit measurements (IL, Delay) from main transmit in port (Main Tx) to main antenna port (Main Ant). The fourth table starts at byte 199 to byte 234 (Table 15: EEPROM Transmit Data Format). DDM Diversity Transmit Parameter Data

The div transmit parameters denote relevant transmit measurements (IL, Delay) from div transmit in port (Div Tx) to div antenna port (Div Ant). The fifth table starts at byte 235 to byte 270 (Table 15: EEPROM Transmit Data Format).

DDM Absolute Group Delay Parameter Data

The Absolute Group Delay parameters denote relevant absolute delay within both the full TX band from main and div transmit in port (Main Ant and Div Ant) to main and div antenna port (Main Ant and Div Ant) and the full RX band from Main and div antenna port (Main Ant and Div Ant) to main and div receive output port (Main Rx1, Main Rx2, Main Rx3, Main Rx4 and Div Rx1, Div Rx2, Div Rx3, Div Rx4)

UMTS 2100 DDM-3 Technical Specification

UMT/BTS/DD/016933 V01.05/EN Standard 09/02/2007 Page 40/84

The sixth table starts at byte 271 to byte 309 (Table 16: EEPROM Absolute Group Delay Data Format).

Each table requires a 16-bit CRC calculated over a specified number of data bits, which corresponds to the table data size. The calculated CRC is MSB first. The generator polynomial is g(x)=x^^16+x^^12+x^^5+1. The resultant is stored in the two byte CRC respective location (see Appendix 3 for CRC Calculation Code). All signed integer data (I8) is stored with the MSB reserved for the bit of sign. The allocated bytes within each table, which are unused, must be filled with the equivalent of a zero integer in the denoted format. The unused bytes filled with the equivalent zeros must be the most significant bytes of the allocated memory location.

Table 29: Dependability Targets

11.3 DEPENDABILITY DEFINITIONS

Corrective action An action that results from a process or DDM failure and directly prevents that particular failure from recurring.

Containment An action that prevents a particular failure escaping from the supplier’s factory.

Critical Impacts the ability of the system to process calls.

Defect A defect is defined as any condition associated with the DDM that is not in compliance with the requirements of this document. Cosmetic defects are not generally included in this measurement, unless they are judged serious enough to preclude the use of the DDM for normal field service.

Defect density The expected density of defects per thousand lines of executable software code in the DDM (defects/KLOEC).

Dependability Ensuring that the customer gets what they want, when they want it. The DDM works when it gets there and keeps on working. If anything does go wrong, it gets fixed quickly.

DOA Dead on Arrival. Any DDM that is unusable by ALU or ALU’s customers before commissioning is completed, including cosmetic defects, storage and shipping damage.

ESS Environmental Stress Screening is a production screen that uses stresses that are higher than those

Page 62: DDM-3 Specifications V01.05

experienced in normal use to precipitate defects before the DDM is shipped.

FIT Failures in time. This is a smaller unit of reliability, used for components. It is the number of failures in 109 hours.

FMECA Failure modes, effects, criticality analysis. This is a design walkthrough that examines potential failures and determines the effects of those failures, the ability of the system to detect those failures, and the ability of the system to identify the FRU from which they originate. The result is a probability of detecting failures (in-service fault detection) and isolating failures (in-service fault isolation).

FR Failure rate is the percent of DDMs per year (%/yr) that experience electrical functional failure at customer's sites (field). This rate is taken into account only after the initial site installation and commissioning period has ended. The failure rate should take into account both hardware and software failure modes.

FRU Field Replaceable Unit. The physical unit that the customer would return. It contains one or more circuit packs or OEM devices.

HALT Highly accelerated life test. HALT is a series of tests performed beyond the product specifications in order to precipitate weak components or design.

HASS See ESS

In-service fault detection The probability of detecting a fault in the DDM while it is in service. A high level of detection will reduce the average time to repair the system.

In-service fault isolation The probability of isolating a fault to the FRU while it is in service. A high level of detection will reduce the average time to repair the system and reduce NFFs.

L10 A measure of useful life, it is the point in time (years) at which 10% of the population is predicted to fail due to wear out. It indicates the beginning of a rapid wear out ramp.

MTBF Mean Time Between Failures. The calculated average time (hours) between failures, used as a relative

NFF No fault found. NFF refers to product returned from the customer where the reason for return cannot be determined. NFFs can be caused by poor isolation of faults by the system, poor correlation of factory test sets to field conditions, and difficult return processes, among other causes.

POS Proof of screen; proof of effectiveness of HASS/ESS

Preventative action Going beyond corrective action, a preventative action prevents the recurrence of a class of fault. A preventative action usually changes a behavior or a process.

RR Return rate. Return rate is the percent of products per year (%/yr) that are returned from the end customer to ALU for any reason. This could include NFF, functional failure, intermittent failure, cosmetic damage, damage in shipment, incorrect vintage, etc.

SPQL Shipped Product Quality Level. The shipped product quality level refers to the portion of the annual defective DDM compared to the total annual shipped DDM which are discovered during factory audits and during DDM installation. It is expressed either in PPM or %. It is also referred to as out of box quality, average outgoing quality level, or DOA.

Useful Life This is the period of time (in years) that the DDM is expected to operate in normal field service when used in the operational environment specified in this document. The materials, technologies and design practices used in the manufacture of this product must be chosen appropriately to meet this useful life requirement.

The configuration of the unit that has passed the qualification tests shall be appropriately documented in a production file. This production file shall be available for audits at the supplier factory. Any subsequent change that may affect product qualification must be submitted to ALU. Preliminary agreement must be obtained from ALU before the change can be implemented. Sufficient information shall be provided in order for a decision to be made.

13.2.1 CHANGE MANAGEMENT REQUIREMENTS

13.2.1.1 VENDOR RESPONSIBILITIES

Once the equipment has been accepted as a ALU sub-assembly, the vendor shall perform no further changes except after agreement with ALU. The vendor shall develop a “Manufacturing baseline” with ALU, which clearly defines the criteria requiring ALU Change Management approval. The vendor shall notify the designated ALU component-engineering prime for the DDM of any change to the design or manufacture of the DDM. The vendor shall require the written approval from the designated ALU component engineer for any change covered by the Manufacturing Baseline. No change shall impact any of the performance criteria defined in this document. Any documentation supporting regulatory updates and specification conformance maintenance shall be provided to ALU. The ALU EC process shall manage changes.

13.2.1.2 CHANGES TO ALU PRODUCT RELEASE NUMBER

Page 70: DDM-3 Specifications V01.05

UMTS 2100 DDM-3 Technical Specification

UMT/BTS/DD/016933 V01.05/EN Standard 09/02/2007 Page 70/84

13.2.3 PRODUCT CHANGES

Product or process changes will be partitioned into three categories: � Class I permissive changes � Class II permissive changes � All other changes

All are subject to the requirements and guidelines identified in NPS50561 General Requirements for OEM Equipment, especially the section titled "Change of Product or Process", and to the requirements in FCC and DOC regulations.

13.2.3.1 CLASS I PERMISSIVE CHANGES (ONLY APPLICABLE TO FCC)

Class I permissive changes refer to modifications which “... do not change the equipment characteristics beyond the rated limits established by the manufacturer...” [FCC Part 2 Subsections J]. The utilization of this feature of the regulatory process expedites type acceptance of the DDM by using prototype hardware and hence allows for the concurrent activities of regulatory approval and completion of the design cycle. Subsequent vendor cost reductions, yield improvements, etc. also benefit. Class I permissive changes by the vendor must include the following: Provision of a record of the change which must be kept on file by the vendor. It is the vendor’s responsibility to ensure that all requirements for FCC permissive changes are met.

13.2.3.2 CLASS II PERMISSIVE CHANGES

Class II permissive changes refer to modifications which bring the performance of the equipment outside the manufacturer’s rated limits as originally filed but not below the minimum requirements of the applicable rules...” [FCC Part 2 Subsection J]. Since a Class II permissive change would require alteration of this document, the changes would need to be discussed at length with ALU.

13.2.3.3 OTHER CHANGES

All other changes require a new regulatory filing.

15 APPENDIX 1 : IMD LEVEL CALCULATION

The 3GPP 25.104 specifies a sensitivity at :

121 dBm/12.2 kHz (one DCH at 12.2kb/s).

When an interfering signal is present at the BS antenna input, the sensitivity of the BTS must not be degraded more than 6dB. This leads to a max Interfering RF level of : -100dBm/3.84MHz at the LNA input (-77dBm at the LNA output, worst case). Recall : Sensitivity = -174 +10log(12.2Khz) +NF + Eb/N1 + Margin = -121 dBm/12.2KHz (N1 = noise level at the input of the RX chain with Eb/N1 = 5dB NF = 5dB Margin = 2dB)

18 APPENDIX 4 : UMTS SIGNAL DESCRIPTION

18.1 OVERVIEW

The UMTS signal is the sum of several distinct QPSK signals. The following table is for information only.

Signal type Meaning Quantity Power

PSCH Primary Synchronization Channel 1 fixed

SSCH Secondary Synchronization Channel 1 fixed

PCPICH Primary Common Pilot Channel 1 fixed

PCCPCH Primary Common Control Physical Channel 1 fixed

SCCPCH Secondary Common Control Physical Channel 1 up to 128 controlled

AICH Acquisition Indicator Channel 1 up to 128 controlled

PICH Paging Indicator Channel 1 up to 128 controlled

DPDCH Dedicated Physical Data Control Channel 1 up to 128 controlled

DPCCH Dedicated Physical Common Control Channel 1 up to 128 controlled

All these signals are synchronous. The Clock frequency is 3.84 MHz. The maximum number of simultaneous signals is approximately 110. So the composite signal is amplitude and phase modulated.

18.2 UMTS SIGNAL FOR DDM TEST

The UMTS signal is amplitude modulated and phase modulated at a chip rate of 3.84MHz for one UMTS transmitted carrier. The envelop magnitude of the signal can change with the chip rate (TM1 one carrier) and can also changed accordingly with the slot rate (DTX) or the frame rate (COMPRESS or TM1+IDLE MODE). The rms power variation for DTX and COMPRESS are due to the management of the data control channel during the slot time or frame time part. To perform a MCPA qualification (compliance with all the specification), different test files have been built. These test files have been built to focus on two objectives:

• First: in order to check the MCPA electric characteristics on basic 3GPP test files (see tests model 1 to 5). They include 3GPP standard plus a ALU algorithm, which allows decreasing the Peak to Average Ratio (PAR). These files are built to be compliant with the 3GPP requirements (see reference documentation). They are used as reference to compare results between Supplier and ALU.

Page 81: DDM-3 Specifications V01.05

UMTS 2100 DDM-2 Technical Specification

UMT/BTS/DD/016933 V01.05/EN Standard 09/02/2007 Page 81/84

• Second: in order to check the MCPA dynamic behavior (averaging power change versus the time), other files were built to fit steady averaging power variations (DTX, Compress). In order to fit different averaging power variations, with different recursive times, a new test (see chapter Amplitude limited RF power burst) was added using a pulse generator to remote an input attenuator at the MCPA input. All these tests are performed to check the MCPA robustness against the averaging power variations. These tests can not represent all the cases which occur in the field but according to the ALU experience they give a sufficient level of confidence to ensure that the MCPA is robust enough to operate with the “real word” UMTS signal.

Note: The Supplier is responsible of its design and ALU assumes that the Supplier knows perfectly the strength and the weakness of it. It means that it is the responsibility of the Supplier to build other tests to check its design and to ensure that no issue will occur in the field in the” real word” representative of 3GPP (see reference documentation) assuming the peak power ratio is within the range defined by the ALU specific tests files. If some issues occur in the field, during the product life, due to particular signal (assuming it reflects the real word representative of the 3GPP specification see reference documentation), ALU will have the right to build a new file to fit the field failure condition. This new file could be used to check the correction after having found an agreement with the Supplier to validate the harmony with the 3GPP specification. The different test files are given hereafter in the following paragraph and are related to specific measurements:

18.2.2 OTHER DYNAMIC TESTS:

These tests are dedicated to check the MCPA behavior on RF UMTS signal which have their envelope modulated by a rectangular AM waveform. The UMTS signal can have its averaging power level depending of the time slot (or multiple time slots) and the whole combinations cannot be covered by only few defined test files as “Compress” or “TM5-light-01-01-2005”. The following requirements allow testing the MCPA robustness for different AM rectangular waveforms. The tables below give an overview of the different combinations: Table1: Pseudo compress mode cases

Deep attenuation 0dB / 3.5dB / 7dB

Attenuation duration 3 / 7 / 14 slots

Time recurrence 40ms to 200ms

Note: Slot=666µs Table2: Pseudo HSDPA mode cases

Deep attenuation 0dB / 3.5dB / 7dB

Attenuation duration 2ms to 40ms

Time recurrence 2ms to 40ms

These tests are dedicated to control the following parameters:

• ACLR

• SEM

• Spurious emissions

Notes: The SEM and ACP values must be compliant with the ALU requirement for the entire output power range. The minimum and the maximum RF output averaging power (long time integration) will have to be chosen to satisfy the two rules:

• The RF output power during the low power period must be at minimum 25dBm.

• The RF output power during the high power period must be at maximum 46,5dBm.

18.2.2.1 IDLE RF BTS MODE

To give to the handy UMTS phone the possibility to receive others BTS in its area, the 3GPP requires having an idle mode (RF mute) which is defined as following: -RF attenuation 35 dB minimum on the antenna. -Length of the idle mode between either 0.5 slot or 1 slot (1 slot = 666µs). -Repetition of the idle mode can be 5,7,10,15,20,30,40,50 frames of 10 ms. In these conditions, no alarm must be reported. Note: The BTS is in idle mode when no RF is present on its antenna. To do that, the baseband signal is decreased by 30dB in order to have the same 30dB of attenuation at the antenna. So, in idle mode, the MCPA must be able to keep its set points of its different loops to ensure to have always a good RF spectrum when the RF comes back. The RS485 link cannot be use to warn MCPA when the RF idle mode is activated because the rate of this link is too slow. Conditions of test: The MCPA must be tested with the signal file “Test model 1” with 1 carrier. The generator (E4433B) must be able to pulse the RF signal with the following setting which are considered as the worst case for the MCPA: Width pulse: 49.4ms Period pulse: 50ms The MCPA will be supposed to have the same behavior with the other idle mode repetition
