1. Overview

The NX-220 is a VHF portable transceiver designed to operate in the frequency range of 136 to 174MHz. The unit consists of a receiver, transmitter, phase-locked loop (PLL) frequency synthesizer, baseband parts, power supply, and control circuits.

2. Frequency Confi guration

The receiver is a double-conversion superheterodyne using the first intermediate frequency (IF) of 49.95MHz and the second IF of 450kHz. Incoming signals from the antenna are mixed with the local signal from the PLL circuit to produce the fi rst IF of 49.95MHz. This is then mixed with the 50.4MHz second local oscillator output to produce the 450kHz second IF. The transmit signal frequency is gener-ated by the PLL VCO, and modulated by the signal from the DSP. It is then amplifi ed and fed to the antenna.

3-1. RF circuitAn incoming RF signal from the antenna terminal is

passed through the antenna switch (D102, D103, D105 and D106) and then the band-pass fi lter (L212, L213). The band-pass fi lter is adjusted by a variable capacitor. The input volt-age to the variable capacitor is regulated by the voltage out-

put from the D/A converter (IC4). The signal is amplifi ed by an RF amplifi er (Q202), and passed through the band-pass fi lter (L207, L208 and L211). The resulting signal is applied to the fi rst mixer (Q201), where it is mixed with the fi rst lo-cal oscillator signal output from the frequency synthesizer to produce the fi rst IF (49.95MHz).

3-2. IF circuitThe fi rst IF signal is passed through a four-pole monolithic

crystal fi lter (XF1) to reject adjacent channel signals. The fi l-tered fi rst IF signal is amplifi ed by the fi rst IF amplifi er (Q303) and then applied to the IF system IC (IC302). The IF system IC provides a second mixer, AGC amplifi er, and RSSI (Re-ceived Signal Strength Indicator).

The second mixer mixes the first IF signal with the 50.4MHz of the second local oscillator output and produces the second IF signal of 450kHz.

The second IF signal is passed through the ceramic fi lter (CF1) to reject the adjacent channel signal. The fi ltered sec-ond IF signal is amplifi ed by the AGC amplifi er.

The signal from the AGC amplifier is input to the ASIC (IC610) through the ceramic fi lter (CF2).

3-3. Audio amplifi er circuitAudio processing (high-pass filter, low-pass filter, de-

emphasized and so on) at FM mode and decoding at NXDN mode are processed by the DSP. The audio signal from IC610 and IC603 goes through the amplifier (IC904). The signal then goes through an electronic volume control (IC4), and AF amplifi er (IC901).

While AFSW is High, the power supply of audio power amplifi er (IC901) is activated, and the output to the speaker turns ON.

3-4. Squelch circuitIt amplifi es the demodulated noise signal from IC610 af-

ter fi ltering through the LPF and HPF circuit. The amplifi ed signal is then converted to a DC signal by the detection cir-cuit. The converted signal is fed back to IC610.

4-2. Baseband circuitThe audio signal output from the baseband circuit is con-

verted to digital data with a sampling frequency of 48kHz. This digital data is sent to the DSP (IC603), and voice signals of 300Hz or lower and frequencies of 3kHz or higher are cut

off and the audio range of 300Hz to 3kHz is extracted. The audio signal is then pre-emphasized in FM mode and syn-thesized with the signals, such as QT and DQT, as required, and is then output from IC610. In Digital mode, the audio signal is converted to the 4-Level FSK baseband signal and output from IC610. The DTMF and MSK baseband signals are also generated by the DSP and output by IC610

The LPF (IC6) works as a smoothing fi lter. The level out-put according to the transmit carrier is fi ne-adjusted accord-ing to each modulation method.

4-3. VOXThe DSP detects the audio level. If the detected level be-

comes higher than the threshold level, the VOX starts.

4-4. Drive and Final amplifi erThe signal from the T/R switch (D413 is on) is amplifi ed

by the pre-drive amplifier (Q102) to 16~17dBm. It makes it possible to spoil input to the drive amplifier by control-ling the power supply of the pre-drive amplifier with the PD switch (Q110). The output of the pre-drive amplifi er is amplifi ed by the drive and fi nal amplifi ers (Q103, Q104) to 5.0W (1.0W when the power is low). Q103 and Q104 are MOS FETs. The output of the fi nal amplifi er is then passed through the harmonic fi lter (LPF) and antenna switch (D102, D103 are on) and applied to the antenna terminal.

4-5. APC circuitThe APC circuit always monitors the current flowing

through the RF power amplifi er (Q104) and keeps a constant current. The voltage drop at R153, R154 and R155 is caused by the current fl owing through the RF power amplifi er and this voltage is applied to the differential amplifier (IC101 1/2). IC101 (2/2) compares the output voltage of IC101 (1/2) with the reference voltage from IC610, and the output of IC101 (2/2) controls the VGG of Q103 and Q104 to make the both current constant. The change of power high/low is car-ried out by the change of the reference voltage. Q106, Q107 and Q108 are turned on and Q105 and Q109 are turned off during transmission and the APC circuit is active.

5. PLL Frequency Synthesizer

5-1. TCXO (X401)The TCXO (X401) generates a reference frequency of

16.8MHz for the PLL frequency synthesizer. This reference frequency is applied to pin 9 of the PLL IC (IC403) and is connected to the IF circuit as a 2nd local signal through the Tripler (Q301).

The frequency adjustment is achieved by switching the ratio of dividing frequency. The resolution of the adjusting frequency is approximately 4Hz.

5-2. VCOThere is a RX VCO and a TX VCO.The TX VCO (Q402) generates a transmit carrier and the

RX VCO (Q401) generates a 1st local signal. For the VCO oscillation frequency, the transmit carrier is 136 to 174MHz and the 1st local receive signal is 185.95 to 223.95MHz.

The VCO oscillation frequency is determined by one sys-tem of operation switching terminal “T/R” and two systems of voltage control terminals “CV” and “ASSIST”.

The operation switching terminal, “T/R”, is controlled by the control line (/T_R) output from the ASIC (IC610). When the /T_R logic is low, the VCO outputs the transmit carrier and when it is high, it outputs a 1st local receive signal.

The voltage control terminals, “CV” and “ASSIST”, are controlled by the PLL IC (IC403) and ASIC (IC610) and the output frequency changes continuously according to the applied voltage. For the modulation input terminal, “VCO_MOD”, the output frequency changes according to the applied voltage. This is used to modulate the VCO output. “VCO_MOD” works only when “/T_R” is low.

5-3. PLL IC (IC403)The PLL IC compares the differences in phases of the

VCO oscillation frequency and the TCXO reference frequen-cy, returns the difference to the VCO CV terminal and real-izes the “Phase Locked Loop” for the return control. This allows the VCO oscillation frequency to accurately match (lock) the desired frequency.

CIRCUIT DESCRIPTION

NX-220

15

When the frequency is controlled by the PLL, the fre-quency convergence time increases as the frequency differ-ence increases when the set frequency is changed. To sup-plement this, the ASIC is used before control by the PLL IC to bring the VCO oscillation frequency close to the desired frequency. As a result, the VCO CV voltage does not change and is always stable at approximately 2.5V.

The desired frequency is set for the PLL IC by the ASIC (IC610) through the 3-line “SDO1”, “PCK_RF”, “/PCS_RF” serial bus. Whether the PLL IC is locked or not is monitored by the ASIC through the “PLD” signal line. If the VCO is not the desired frequency (unlocked), the “PLD” logic is low.

The modulation signal of the Low-speed data is applied to pin 23 of the PLL IC (IC403).

The modulation signal is digital data of a sampling fre-quency of 96kHz set for the PLL IC by the DSP (IC603) through the “PLLMOD” line.

5-4. Local switch (D412, D413)

The connection destination of the signal output from the buffer amplifier (Q408) is changed with the diode switch (D413) that is controlled by the transmission power supply, 50T, and the diode switch (D412) that is controlled by the receive power supply, 50R. If the 50T logic is high, it is con-nected to a send-side pre-drive (Q102). If the 50T logic is low, it is connected to a receive-side mixer (Q201).

6. Control Circuit

The control circuit consists of the ASIC (IC610) and its pe-ripheral circuits. IC610 mainly performs the following:1) Switching between transmission and reception by PTT

signal input.2) Reading system, zone, frequency, and program data from

the memory circuit.3) Sending frequency program data to the PLL.4) Controlling squelch on/off by the DC voltage from the

squelch circuit.5) Controlling the audio mute circuit by decode data input.

6-1. ASICThe ASIC (IC610) is a 32-bit RISC processor, equipped

with peripheral function and ADC/DAC.This ASIC operates at 18.432MHz clock and 3.3V/1.5V

DC. It controls the fl ash memory, SRAM, DSP, the receive circuit, the transmitter circuit, the control circuit, and the dis-play circuit and transfers data to or from an external device.

6-2. Memory circuitThe memory circuit consists of the ASIC (IC610), the

SRAM (IC605), and the flash memory (IC601). The flash memory has a capacity of 32M-bit that contains the trans-ceiver control program for the ASIC and stores the data. It also stores the data for transceiver channels and operating parameters that are written by the FPU. This program can be easily written from external devices. The SRAM has a capacity of 1M-bit that contains work area and data area.

■ Flash memoryNote: The fl ash memory stores the data that is written by the FPU (KPG-141D), tuning data (Deviation, Squelch, etc.), and firmware program (User mode, Test mode, Tuning mode, etc.).

■ SRAM (Static memory)Note: The SRAM has a temporary data area and work area.

6-3. LCDThe LCD is controlled using the 4 serial lines (SDI0, /

LCDCS, SCK0, SDO0) from the ASIC (IC610).

6-4. Key detection circuitKeys are detected using the LCD controller driver IC (IC8).

If a pressed key is detected by IC8, it is informed to IC610 through the serial line.

6-5. Low battery warningThe battery voltage is divided using R514 and R515 and

is detected by the ASIC (IC610). When the battery voltage falls below the voltage set by the Low battery warning ad-justment, the red LED blinks to notify the operator that it is time to replace the battery. If the battery voltage falls even more (approx. 5.8V), a beep sounds and transmission stops.

Low battery warning Battery condition

The red LED blinks during transmission.

The battery voltage is low but the transceiver is still usable.

The red LED blinks and the warning tone beeps while the PTT switch is pressed.

The battery voltage is low and the transceiver is not usable to make calls.

6-6. DSPThe DSP circuit consists of a DSP (IC603) and processes

the baseband signal. The DSP operates on an external clock of 18.432MHz (the same as the IC610), the I/O section op-erates at 3.3V and the core section operates at 1.5V. The DSP carries out the following processes: • 4 Level FSK processing • Analog FM pre-emphasis/de-emphasis • Vocoder processing between audio codec and modula-

tion/demodulation • CAI processing, such as error correction encoding • QT/DQT encoding/decoding • LTR encoding/decoding • DTMF encoding/decoding • MSK encoding/decoding • 2-tone encoding/decoding • 5-tone encoding/decoding • Compressor/expander processing • Voice scrambler processing • Transmit/receive audio fi ltering processing • Microphone amplifi er AGC processing • Audio mute processing • Modulation level processing

7. Power Supply Circuit

The battery voltage (+B) is provided from the battery terminal on the TX-RX unit (X57). The battery voltage passes through the 2.5A fuse (F1), and goes to the RF fi nal ampli-fi er, AVR ICs (IC504, IC902), DC/DC converter (IC506), and voltage detector IC (IC507). The voltage detector watches the battery voltage. If the battery voltage is 5.6V or higher, the detector outputs High.

When the VOL SW is turned on, SB1 becomes high (bat-tery voltage). DC/DC (IC506) operates if both SB1 and the output of the detector are high. IC506 outputs 3.8V and activates IC502 (33M), IC503 (15M), IC501 (33A) and IC505 (33C). As a result, the ASIC and DSP operate.

The SBC signal becomes High after the ASIC operates, IC504 (50C), IC902 (50V) and Q501 (SB2) are turned on.

When the /SAVE signal becomes High, Q512 (50C) oper-ates. Switches (Q503, Q505) are controlled by the ASIC. Q505 (50T) is turned on in transmit mode. Q503 (50R) is turned on in receive mode.

When the VOL SW is turned off, the /PSW signal be-comes Low. After detecting the /PSW signal, the ASIC changes the SBC signal to Low.

50C is fed to IC509 (100C). IC509, D511 and D512 con-sist of a voltage doubler. C543 is charged to 5V by 50C and switched to C545 by the “DDCLK” control signal. The 100C circuit then outputs approximately +10VDC.

8. Signaling Circuit

8-1. Encode (QT/DQT/LTR/DTMF/2-tone/5-tone/MSK)Each signaling data signal of QT, DQT, LTR, DTMF,

2-tone/5-tone and MSK is generated by the DSP circuit, su-perimposed on a modulation signal and output from IC610. Each deviation of the TX QT, DQT, LTR, DTMF, 2-tone/5-tone and MSK tone is adjusted by changing the output level of IC603 and the resulting signal is routed to the VCO and PLL.

8-2. Decode (QT/DQT/LTR/DTMF/2-tone/5-tone/MSK)The audio signal is removed from the FM detection signal

sent to the DSP circuit and the resulting signal is decoded.

9. Compander Circuit

The term “compander” means compressor and expand-er. The compander reduces noise by utilizing a compressor and an expander. The transceiver contains a DSP (IC603) to perform this operation. The transceiver compander can be turned on or off using the FPU.

Fault Diagnosis of the BGA (Ball Grid Array) IC

■ Overview A fl owchart for determining whether or not the transceiver can be powered on (the LCD does not function even if the power

switch is turned on) due to broken BGA parts.

■ BGA partsASIC (IC610), DSP (IC603), FLASH (IC601), SRAM (IC605)

When the BGA IC is problematic, please bring the printed circuit board (X57-8040-11) in for service. Various ESN/default ad-justment values are written on the printed circuit board for service.

Additionally various ESN stickers are included. (Please refer to pages 33 and 34.) After the printed circuit board has been readjusted, please attach any ESN stickers to the chassis. When “ESN Validation” is

used with Trunking, you must modify the ESN register.

■ After Changing the PCB1. After changing the printed circuit board, write the up-

to-date Firmware following the instructions in the “RE-ALIGNMENT - 6.Firmware Programming Mode”.

• Write the Firmware in accordance to the Market. If you write different Market Firmware, there are times com-munication with the FPU is not possible.

2. Using the KPG-141D, select your desired item (Model Name and Frequency) from the Model> Product Informa-tion menu, then use Program> Write Data to the Trans-ceiver to write the FPU data (PC Programming mode). When writing to the transceiver, a Warning Message, corresponding to the item selected, appears. Click [OK] to continue writing the data.

3. Enter Program> Test Mode, then adjust the various ad-justment data (PC Test Mode) as described in the “AD-JUSTMENT”.

TROUBLE SHOOTING

4. Attach the new labels corresponding to the new printed circuit board. (Refer to the images below for label place-ment.)

5. If necessary, write the FPU data used by the customer with the KPG-141D.

Note:• When using the ESN Validation function of Trunking, the

ESN number changes when the circuit board is changed (the number is written on the circuit board); the Trunking System cannot be accessed. Maintain the ESN data of the Trunking System following the new ESN.

• When a new printed circuit board is used, the Kenwood ESN changes, as does the Transceiver Information display of the KPG-141D, but this does not have any effect on the operation of the transceiver.

• If changing to the original ESN, please contact our service center.

■ Antenna connector adapterThe antenna connector of this transceiver uses an SMA

terminal.Use an antenna connector adapter [SMA(f) – BNC(f) or

SMA(f) – N(f)] for adjustment. (The adapter is not provided as an option, so buy a commercially-available one.)

■ Nut wrenchIn order to turn the volume nut and the channel selector

nut, use a recommendation tool.KENWOOD part No.: W05-1123-00

■ Battery Jig (W05-0909-00)Connect the power cable properly between the battery

jig installed in the transceiver and the power supply, and be sure output voltage and the power supply polarity prior to switching the power supply ON, otherwise over voltage and reverse connection may damage the transceiver, or the power supply or both.

When using the battery jig in user mode, the transceiver assumes that a lithium-ion battery pack is attached to the transceiver. In adjustment mode, battery type detection is not performed.

Note: When using the battery jig, you must measure the voltage at the terminals of the battery jig. Otherwise, a slight voltage drop may occur within the power cable, be-tween the power supply and the battery jig, especially while the transceiver transmits.

11. 8Ω Dummy Load Approx. 8Ω, 3W

12. Regulated Power Supply 5V to 10V, approx. 3A Useful if ammeter equipped

■ Antenna connector adapterThe antenna connector of this transceiver uses an SMA

terminal.Use an antenna connector adapter [SMA(f) – BNC(f) or

SMA(f) – N(f)] for adjustment. (The adapter is not provided as an option, so buy a commercially-available one.)

■ Nut wrenchIn order to turn the volume nut and the channel selector

nut, use a recommendation tool.KENWOOD part No.: W05-1123-00

■ Battery Jig (W05-0909-00)Connect the power cable properly between the battery

jig installed in the transceiver and the power supply, and be sure output voltage and the power supply polarity prior to switching the power supply ON, otherwise over voltage and reverse connection may damage the transceiver, or the power supply or both.

When using the battery jig in user mode, the transceiver assumes that a lithium-ion battery pack is attached to the transceiver. In adjustment mode, battery type detection is not performed.

Note: When using the battery jig, you must measure the voltage at the terminals of the battery jig. Otherwise, a slight voltage drop may occur within the power cable, be-tween the power supply and the battery jig, especially while the transceiver transmits.
