17. RF Tx/Rx Path and Test Points
How RF signal is transmitted and received between components on Halley PCB is explained in this section. It is important to realize RF transmission path (Tx) and receiving path (Rx) before starting out to repair NG PCB, because engineers need to choose proper test points which assist us to distinguish where the problem is. The following paragraphs describe both Tx and Rx path in GSM and WCDMA bands. The related test points are listed in the following figures.
17.1 GSM Tx/Rx path and test points
GSM Tx path
Transceiver, RF6001 (U900), receives IQ signals coming from baseband, and output signals of RF6001 Pin22 and Pin23 are transmitted into the buffer of receiver, RF2722. Then RF2722 Pin12 and Pin13 emit the low band signal (GSM900) and high band signals (DCS1800 or PCS1900) separately.
In the low band, output signal from RF2722 Pin12 passes through C917, attenuator (U903) and RF3166 (U904) Pin7, power amplifier, sequentially. Transmission and receiving switch (U902), also named T/R switch, gets the amplified signal from RF3166 Pin23 via matching circuits. RF signal coming from T/R switch Pin15 is transmitted to connector (Con6) and radiated via the GSM antenna of Halley.
In the high band, output signal from RF2722 Pin13 passes through C243, attenuator (U905) and RF3166 (U904) Pin1, power amplifier, sequentially. Transmission and receiving switch (U902), also named T/R switch, gets the amplified signal from RF3166 Pin30 via matching circuits. RF signal coming from T/R switch Pin15 is transmitted to connector (Con6) and radiated via the GSM antenna of Halley.

through connector (Con6) and T/R switch Pin15 (U902) sequentially. There are three output pins of T/R switch, including Pin2, Pin4, and Pin5. The output path which RF signal is transmitted depends on band selection of T/R switch.
In GSM900 band, the output signal which is transmitted from T/R switch Pin2 passes through SAW filter (BPF1) and matching circuits sequentially. Upon RF2722 (U901) receiving the signal, it is amplified in the Low Noise Amplifier (LNA) of the receiver, down converted the signal’s frequency and transformed into IQ signals. The IQ signals from RF2722 Pin20, Pin21, Pin22, and Pin23 travel to the transceiver RF6001 (U900). The transceiver RF6001 transfers the signals to the baseband signals.
In DCS1800 band, the output signal which is transmitted from T/R switch Pin5 passes through SAW filter (BPF4) and matching circuits sequentially. Upon RF2722 (U901) receiving the signal, it is amplified in the Low Noise Amplifier (LNA) of the receiver, down converted the signal’s frequency and transformed into IQ signals. The IQ signals from RF2722 Pin20, Pin21, Pin22, and Pin23 travel to the transceiver RF6001 (U900). The transceiver RF6001 transfers the signals to the baseband signals.
In PCS1900 band, the output signal which is transmitted from T/R switch Pin4 passes through SAW filter (BPF1) and matching circuits sequentially. Upon RF2722 (U901) receiving the signal, it is amplified in the Low Noise Amplifier (LNA) of the receiver, down converted the signal’s frequency and transformed into IQ signals. The IQ signals from RF2722 Pin20, Pin21, Pin22, and Pin23 travel to the transceiver RF6001 (U900). The transceiver RF6001 transfers the signals to the baseband signals.

17.2 WCDMA Tx/Rx path and test points
WCDMA Tx path
The output signal from transmitter MAX2390 Pin2 travels to SAW filter (BPF5), and RMPA2259 Pin2 sequentially. The boosted power coming from RMPA2259 Pin8 passes through isolator (U954), duplexer Pin1 (U956), and connector (Con7). At last, the RF signal is radiated via WCDMA antenna of Halley.
WCDMA Rx path
RF signal in WCDMA, receiving from base stations via the WCDMA antenna, passes through connector (Con7) and duplexer Pin3 sequentially. MAX2391 Pin1 (U958), built-in LNA, receives the signal from duplexer. Then the signal is transmitted to SAW filter (BPF6) and returns to receiver MAX2391 again. After down converting the signal’s frequency and transforming into IQ signals, the IQ signals from MAX2391 Pin20, Pin21, Pin22, and Pin23 travel to baseband.

18. Procedures of Repair
18.1 RF repair’s procedure
The following flow chart shows repair’s procedures that comprise of calibration, pretest, and general repair processes. In order to guarantee existence of RF parameters in FDI, calibration files should be done first. After conductive pretest, engineers can check whether Halley operates properly or not.
Error codes may occur when calibrating or pretest Haley due to poor RF performance. From categorized error codes in the following section, engineers can infer the cause of problem by corresponding error codes, and find out the defect component by using debug tool. There are four kinds of general RF debug, including GSM Tx debug, GSM Rx debug, WCDMA Tx debug and WCDMA Rx debug. Each debug method is described specifically in following sections.

a. Set RF signal generator to emit CW with corresponding frequency and transmit power into Halley GSM connector via a RF cable and a RF adapter (MS-162). Spectrum analyzer connects with a high impedance probe. Execute GSM debug tool and set parameters in the above table.
b. Use the high impedance probe to sequentially measure RF power of test points on GSM Rx path, including L59, C889, and C887. Corresponding locations are shown in “4. RF Tx/Rx Path and Test Points.” Furthermore, measurement error of RF power on each test point is unavoidable due to measurement skills and methods of using high impedance probe. After probing sequential test points, the probable defect component should be checked that DC power is supplied for this component at proper voltage level.
c. L59: Check whether GSM RF connector (CON6) is good or not. CON6 needs to be reworked if no RF signal is measured on L59.
d. C889: Check whether T/R switch (U902) is good or not. T/R switch needs to be reworked if RF signal emitted by the signal generator is measured on L59, and no power is detected on C889. The following figure is an example of C889 signal measurement on the spectrum analyzer.

The purpose of this process is to distinguish problems between antenna and RF circuit that cause weak RF performance. Besides, wireless test is a previous analysis of all RF tests. Moreover, engineers utilize wireless test to confirm that antenna performance is not affected after re-assembling.
The detail steps of process are listed as follows.
a. Put a golden sample of Halley into a shielding box and link to a tester (Agilent 8960 or R&S CMU9020). Then, record its location and path loss.
b. At the same position that the golden sample was located, put problematic Halley into the shielding box. After that, wait for Halley registering at the tester.
c. After attaching to the network, make a phone call.
d. Measure maximum output power and sensitivity. The test requirements of maximum output power and sensitivity shall not exceed the range listed in the following table.
e. If any of previous steps (b. ~ d.) is failed, consequently enter next process, pretest test.
f. If all previous steps (b. ~ d.) are passed, it means that nothing happens. Therefore, need to clarify customer’s complaints and try to understand user’s behaviors.
