■ Top-level description

The RF module performs the necessary high frequency operations of theEGSM900/1800/1900 tripleband (EDGE) engine. Both the transmitter and receiver have been implemented by using direct conversion architecture which means that the modulator and demodulator operate at the channel frequency.

The core of the RF is an application-specific integrated circuit, Honi. Another co re component is a power amplifier module which includes two amplifier chains, one fo r EGSM900 and the other for GSM1800/GSM1900.

Other key components include

• 26 MHz VCTCXO for frequency reference

• 3296-3980 MHz SHF VCO (super high frequency voltage controlled oscillator)

• Antenna switch module (ASM)

• Three SAW filters

• BAW-LNA module

The control information for the RF is coming from the baseband section of the engine through a serial bus, referred later on as RFBus.

The whole RF circuitry is located on one side of the 8-layer PWB. EMC leakage is prevented by using a metal shield with gasket. The RF circuits are separated

into two blocks.

• PA, ASM, TK balun

• Honi RF IC, VCO + balun, VCTCXO, BAW-LNA, Rx filter, Tx filter

The RF transmission lines constitute of striplines and microstriplines after PA.

■ RF implementation in RA-8

Frequency plan

The RF frequency plan is shown below. The VCO operates at the channel fre quency multiplied by two or four depending on the frequency band of operation. This means that the baseband modulated signals are directly converted up to the transmission frequency and the received RF signals directly down to the baseband frequency.

Figure 4: ASM

DC characteristics

Regulators

The transceiver baseband section has a multi function analog ASIC, UEM, which contains among other functions six pieces of 2.78 V linear regulators and a 4.8 V switch ing regulator. All the regulators can be controlled individually by the 2.78 V logic directly or through a control register. Normally, direct control is needed because of switching speed requirement: the regulators are used to enable the RF-functions which means that the controls must be fast enough.

The use of the regulators can be seen in the power distribution diagram which is p resented in Figure 6, “Power distribution diagram,” on page 15.

The seven regulators are named VR1 to VR7. VrefRF01 is used as a reference voltage for Honi.

The regulators (except for VR7) are connected to the Honi. Different modes of operation can be selected inside the Honi according to the control information coming through the RFBus.

RA-8 7 - RF Description and Troubleshooting Nokia Customer Care

RF Troubleshooting

All measurements should be done using a spectrum analyzer with a high-frequency high-impedance passive probe (LO-/reference frequencies and RF power levels) and an oscilloscope with a 10:1 probe (DC-voltages and low frequency signals).

The RF section is build around one RF ASIC (Honi N7500). For easier troubleshooting, this RF troubleshooting document is divided into sections.

Before changing Honi, please check that both supply voltages and serial communication coming from baseband to Honi are OK. Please note that the grounding of the PA module is directly below the PA module, so it is difficult to check or change.

Most RF semiconductors are static discharge sensitive! Therefore ESD protection must be taken care of during repair (ground straps and ESD soldering irons). Honi and PA are moisture sensitive and thus must be handled as described in the Special Component Handling Document.

Apart from key components described in this document there are a lot of discrete components (resistors, inductors and capacitors) of which troubleshooting is done by checking if the sold ering of the component is done properly (for factory repairs checking if it is missing from the PWB). You can check capacitors 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 vary due to different measuring equipment or different grounding of the probe used. When using an RF probe use a pair of metallic tweezers to connect the probe ground to the PWB ground as close to the measurement point as possible.

■ Receiver description and troubleshooting

Each receiver path is a direct conversion linear receiver. From the antenna, the received RFsignal is fed to a front end module where a diplexer first divides the signal into two separate paths according to the band of operation: either lower, EGSM900 or upper, GSM1800/ GSM1900 path.

Most of the receiver circuitry is included in Honi.

Rx front end

The front end features include:

• Antenna 50 ohm input

• RXs single outputs

• TXs single 50 ohm inputs

• 3 control lines from Honi

Antenna

The RA-8 EGSM900/GSM1800/GSM1900 transceiver features an internal antenna.

General instructions for Tx troubleshooting

Please refer to section Service Concepts in Chapter 3, Service Software Instructions. To start Tx troubleshooting:

1. Connect the test jig MJ-83 to a computer with a DAU-9S cable or to an FPS-8 flash prommer with an XCS-4 modular cable.

Make sure that you have a PKD-1 dongle connected to the computer’s parallel port.

2. Connect a DC power supply to the module test jig (MJ-83) with an FLC-2 cable.

Note: When repairing or tuning the transmitter use external DC supply with at least 3A current capability. Set the DC supply voltage to 3.9V and set the jumpe r connector on test jig to "bypass" position.

3. Connect an RF cable to the RF connector of the module test jig (MJ-83) and measurement equipment; or at least a 10dB attenuator, otherwise the PA may be damaged. Use a spectrum analyzer as measurement equipment.

Note: The maximum input power of a spectrum analyzer is +30dBm. It is recommended to use 10dB attenuator on the spectrum analyzer input to prevent any damage.

4. Set the phone module to test jig and start Phoenix service software.

5. Initialize connection to the phone. (Use FBUS driver when using DAU-9S and COMBOX driver when using FPS-8).

■ Synthesizer description and troubleshooting

Frequency synthesizers

The VCO frequency is locked by a PLL (phase locked loop) in to a stable frequency so urce given by a VCTCXO which is running at 26 MHz. The frequency of the VCTCXO is in turn locked into the frequency of the base station with the help of an AFC voltage which is generated in UEM by an 11 bit D/A converter. The PLL is located in Honi and it is controlled through the RFBus.

The required frequency dividers for modulator and demodulator mixers are integrated in Honi. Loop filter filters out the comparison pulses of the phase detector and generates a DC control

voltage to the VCO. The loop filter determines the step response of the PLL (settling time) and contributes to the stability of the loop.

The frequency synthesizer is integrated in Honi except for the VCTCXO, VCO, and the loop filter.

General instructions for synthesizer troubleshooting

To start synthesizer troubleshooting:

1. Connect the test jig (MJ-83) to a computer with a DAU-9S cable or to an FPS-8 flash prommer with an XCS-4 modular cable.

Make sure that you have a PKD-1 dongle connected to the computer’s parallel port.

2. Connect a DC power supply or FPS-8 to the module test jig with a PCS-1 cable.

3. Set the DC supply voltage to 3.6V and set the jumper connector on test jig to "bypass" position.

4. Set the phone module to test jig and start Phoenix service software

5. Initialize connection to the phone. (Use FBUS driver when using DAU-9S and COMBOX driver when using FPS-8).

6. From the File menu, choose “Choose Product”.

7. From the list, select RA-8.

8. From the toolbar, set operating mode to "Local"

9. From the Testing menu, choose “RF Controls”.

10.In the “RF Controls” window:

- Select band "GSM900", "GSM 1800" or "GSM1900" (Default = "GSM900").

- Set Active unit to "Rx" (Default = "Rx").

- Set Operation mode to "Continuous" (Default = "Burst").

- Set Rx/Tx channel to 37 on GSM900 band, 700 on GSM1800 band, 661 on GSM1900 band (Defaults).

Nokia Customer Care 7 - RF Description and Troubleshooting

■ RF tunings after repairs

The following tunings have to be performed after repairs:

• Repairs in the Tx part require "Tx Power Level Tuning".

• When component replacements around the modulator area (RF path from UEM via RF ASIC to RF PA) have been done, "Tx IQ Tuning" is additionally required.

• In general Rx repairs, the front-end always requires "Rx Calibration" and “Rx Band Filter Calibration” for all three bands.

• Repairs in the PLL circuit always require "Rx Calibration" of the low band.

• If the RF ASIC is replaced, all calibrations mentioned above have to be done.

Refer to Chapter 3, Service Software Instructions, for instructions on the above-mentioned tunings.
