RF Troubleshooting

Introduction to RF troubleshooting

Measurements should be done using Spectrum analyzer with high-frequency highimpedance passive probe (LO-/reference frequencies and RF power levels) and Oscilloscope with a 10:1 probe (DC-voltages and low frequency signals)

The RF-section is built around one RF-ASIC (Helgo N500). For easier troubleshooting, this RF troubleshooting document is divided in to sections.

Before changing Helgo, please check following things: Supply voltages are OK and serial communication is coming from baseband to Helgo.

Please note that the grounding of the PA module is directly below PA-module so it is difficult to check or change. Most RF semiconductors are static discharge sensitive! So ESD protection must be taken care of during repair (ground straps and ESD soldering irons). Helgo and PA are moisture sensitive so parts must be pre-baked prior to soldering.

Apart from key components described in this document here are a lot of discrete components (resistors, inductors and capacitors) which troubleshooting is done by checking if soldering of the component is done properly (for factory repairs checking if it is missing from PWB). Capacitor can be checked for shortening and resistors for value by means of an ohmmeter, but be aware in-circuit measurements should be evaluated carefully.

Please be aware that all measured voltages or RF levels in this document are rough figures. Especially RF levels varies due to different measuring equipment or different grounding of the used probe. When using RF probe usually a good way is to use metallic tweezers to connect probe ground to PWB ground as close to measurement point as possible.

Fault finding chart of the receiver

During fault finding, the calibration procedure is used to find out, whether all bands are affected (error in common part of the Rx chain) or only one band (error in a Rx part of the failed band). Take care not to save calibration values to the phone memory, which are out of limits. Find the error first and repair it.

When a defective phone has been calibrated, a possible error in RX front-end might be masked. In that case one can get a reasonable RSSI reading, although the front-end shows excessive losses. If it is not sure that incorrect re-calibration has been made, following steps shall be done:

NPL-4/5 Company confidential

Troubleshooting Instructions Nokia Customer Care

- Check if AGC calibration is within limits

- Check if SNR reading is OK.

- Use an Oscilloscope to check levels of “RXI” and “RXQ”.

The RF ASIC generates only single ended I and Q signals (RXI, RXQ). As the A/D converter in UEM requires two differential signals, an artificial mid voltage is generated from VrefRF02.

The BB part is used to measure those signals by means of RSSI reading. This works only if correct calibration has been carried out in production.

If both RX and TX path seem to be faulty it has to be checked if the synthesizer is working.

The antenna switch has following typical insertion losses in Rx-mode from its input to output ports:

• GSM 850/900: 1.3 dB

• GSM 1800: 1.6 dB

• GSM 1900: 1.6 dB

Rx front-end

The RX front-end includes three SAW filters for GSM 850 [US-variant] or GSM 900 [EUvariant] (Z808), and for both variants GSM1800 (Z807), and GSM1900 (Z806). GSM 850/ 900 and GSM 1800 filters are matched to the corresponding LNA inputs of the RF ASIC (N500) with differential matching network (LC-type). For GSM 1900 an external LNA (V802) improves the noise figure of the receiver. For conversion of the unbalanced output port to the balances input port of the RF ASIC the BALUN (T801) is applied, followed by a differential matching network (LC-type). The SAW filters provide the wanted out-ofband blocking immunity. They have one single-ended (unbalanced) input port and two balanced output ports each.

The SAW filters have approximately 2.5 to 3.2 dB insertion losses. The LNA for the GSM 1900 band provides a gain of approximately 17 to 20 dB.

RX paths of RF ASIC

The balanced GSM 850/900 and GSM 1800 RX signals are amplified by one integrated LNA for each band and the subsequent pre-gain stages. The GSM 1900 signal is fed to the pre-gain stage also used for the GSM 1800 signal. After amplification the RX signals are down-converted.

The RX paths of the RF ASIC consist of following sub units:

• Separate LNAs for each of the bands: GSM 850/900, and GSM1800.

• Two PRE-GAIN amplifiers, one for GSM 850/900 and one for GSM1800 and GSM1900.

• Two passive I/Q mixers (MIX), one for GSM 850/900 and one for GSM1800 and GSM1900.

General instructions for transmitter troubleshooting

Connect the phone to a PC, which has Phoenix Service Software and a dongle installed, using either

• Repair jig and DAU-9S (RS232) cable or

• DAU-9T cable (RS232) or

• DKU-5 cable (USB).

Connect the phone to a power supply (DC voltage of 3.9V) and switch the phone on. The value of the DC voltage of 3.9V at the phone battery connector is crucial.

Attention: When repairing or tunning transmitter use external DC supply with at least 3A current capability.

Connect an RF cable between the test jig and the measurement equipment (GSM test equipment, power meter, spectrum analyzer, or similar).

Make use of an adequate attenuator at the input of your measurement equipment (10dB to 20dB are recommended for a spectrum analyzer or a power meter). Additionally, a DC block is recommended. Assure not to overload or destroy the equipment.

Start Phoenix Service Software and open FBUS connection:

Select->Scan Product->Ctrl-R

and wait until phone information is shown in the lower right corner of the screen.

Follow the instructions in the chapters below.

Transmitter troubleshooting

Antenna switch (TX/RX switch)

The antenna switch operates as a diplexer for the RX and TX signals. Moreover, it suppresses the TX harmonics generated by the PA. The antenna switch is a controlled by the RF ASIC using the control signals VANT1, VANT2 and VANT3.

The table below shows the possible different switching states.

To switch the TX -GSM 1800/1900 path both signals VANT2 and VANT3 have to be activated. This increases the isolation from the TX-GSM 1800/1900 path to the RX-GSM 1800 path and reduces the feed back of RF-power to the RF ASIC.

The tuning sensitivity of the VCO is typically 250MHz/V. The typical relation of VCO frequency and tuning voltage is shown in the following diagram:

Reference oscillator 26 MHz (VCTCXO)

The reference oscillator is implemented as Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) module. The component (G501) is located in the Small Signal chamber.

The reference oscillator has two functions:

Company confidential NPL-4/5

Nokia Customer Care Troubleshooting Instructions

• Reference frequency for the PLL synthesizer .

• System clock for BB (signal VCTCXO = 26 MHz, output REFOUT of the Helgo ASIC N500).

For an error free initial synchronization, the 26MHz frequency of the reference oscillator must be accurate enough. Therefore, an analog voltage with signal name AFC tunes the oscillator.

The AFC voltage is calculated using the values “AFC value” and “AFC slope”, which are determined during Rx calibration of the low band.

Voltage Controlled Oscillator (VCO)

The VCO is able to generate frequencies in the range of 3296MHz to 3980MHz when the PLL is working properly. The frequency of the VCO signal is divided by 2 or by 4 in the RFASIC. This allows the generation of all the frequencies in the GSM850, GSM900, GSM1800 and GSM1900 bands, both RX and TX range.

The output frequency of the VCO is controlled by a DC voltage (Vc) of the PLL loop filter. The valid range of Vc is 0.7V– 3.8V when the PLL is in steady state. The typical tuning sensitivity is 250MHz/V.

Even if the PLL is not working properly (Vc outside the valid range), a frequency at the output of the VCO can be detected between 3GHz and 4.4 GHz (if the VCO itself is ok and the supply voltage VR7 = 2.78V is available).
