1 Instruction

This Service Repair Documentation is intended to carry out repairs on Siemens repair level

2.5. The described failures shall be repaired in Siemens authorized local workshops only.

All repairs have to be carried out in an ESD protected environment and with ESD protected

equipment/tools. For all activities the international ESD regulations have to be considered.

Assembling/disassembling has to be done according to the latest A70, A75 Level 2 repair

documentation. It has to be ensured that every repaired mobile Phone is checked according

to the latest released General Test Instruction document (both documents are available in the

Technical Support section of the C-market).

Check at least weekly C-market for updates and consider all A70, A75 related Customer

Care Information, and Repair Information who are relevant for A70, A75.

A70 Partnumber on IMEI label: S30880-S2770-#xxx

A75 Partnumber on IMEI label: S30880-S2790-#xxx

, while # may be any letter (A-Z) and xxx may be any number from 100, 101, 102....

Scrap Handling: All Scrap information given in this manual are related to the

SCRAP-Rules and instructions.

Attention: Consider the new "LEAD-FREE" soldering rules (A70 and A75 affected)

(available in the communication market), avoid excessive heat.

If you have any questions regarding the repair procedures or technical questions spare not

hesitate to contact our technical support team in Kamp-Lintfort, Germany:

6 Radio Part

The radio part is realizes the conversion of the GMSK-HF-signals from the antenna to the

baseband and vice versa.

In the receiving direction, the signals are split in the I- and Q-component and led to the D/A-

converter of the logic part. In the transmission direction, the GMSK-signal is generated in an

Up Conversion Modulation Phase Locked Loop by modulation of the I- and Q-signals which

were generated in the logic part. After that the signals are amplified in the power amplifier.

Transmitter and Receiver are never active at the same time. Simultaneous receiving in the

EGSM900 and GSM1800 band is impossible. Simultaneous transmission in the EGSM900

and GSM1800 band is impossible, too. However the monitoring band (monitoring timeslot) in

the TDMA-frame can be chosen independently of the receiving respectively the transmitting

band (RX- and TX timeslot of the band).

The RF-part is dimensioned for triple band operation (EGSM900, DCS1800, PCS19000)

supporting GPRS functionality up to multiclass 8.

The RF-circuit consists of the following components:

•Hitachi Bright VI E chip set (HD155165BP) with the following functionality:

oPLL for local oscillator LO1 and LO2 and TxVCO

oIntegrated local oscillators LO1, LO2

oIntegrated TxVCO

oDirect conversion receiver including LNA, DC-mixer, channel filtering and

PGC-amplifier

o26 MHz reference oscillator

•Hitachi LTCC transmitter power amplifier with integrated power control circuitry

•Hitachi Frontend-Module including RX-/TX-switch and EGSM900 / DCS1800 / PCS

1900 receiver SAW-filters

•Quartz and passive circuitry of the 26MHz VCXO reference oscillator
