3. TECHNICAL BRIEF

3.1 ReceiverThe receiver part consists of a dual band(GSM & DCS) antenna switch, two RF SAW filters, aexternal dual RF VCO and a transceiver IC(TRF6150). All active circuits for a complete receiverchain with the exception of RF VCO are contained in the transceiver IC(TRF6150).

The TRF6150 chip set has direct conversion structure, so the received RF signal is directlyconverted to base band I and Q signal by the transceiver IC(IF frequency is 0 Hz), which containstwo LNAs and three direct conversion demodulators for E-GSM, DCS and PCS. The demodulated Iand Q signals pass two base band AGC amplifiers and a channel filter, which are on both I and Qsignal paths. The RF front-end circuit is shown Fig. 3-1.

3.1.1 RF front end

RF front end consists of an antenna, a dual band antenna switch, two RF SAWs and two LNAs forE-GSM, DCS band, which are contained in the transceiver IC (TRF6150).

The RF received signals (GSM 925MHz ~ 960MHz, DCS 1805MHz ~ 1880MHz) are input via theantenna or coaxial connector. An antenna matching circuit is between the antenna and theconnector.

VC2 that are connected to 4-Input NOR Gate (U607) to switch either TX or RX path on. When theRX path is turned on, the received RF signal, which has passed through the dual band antennaswitch, is filtered by an appropriate RF SAW filter for better stop band rejection. The filtered RFsignal is amplified by an LNA integrated in the transceiver IC(TRF6150) and pass to a directconversion demodulator. This process is thecsame both GSM and DCS.

The logic and current is given below. Table 3-1.

Table 3-1. The logic and current

3.1.2 Demodulator and Baseband Processing

IF stage is not necessary in this system because the receiver is based on direct conversionarchitecture. So the RX LO frequency is the same as input radio frequency. The amplified signal atLNA stage passes to a direct conversion demodulator and is mixed down to generate I&Q BBsignals. The BB I&Q signals pass via two integrated baseband amplifiers with digitallyprogrammable gain and two fully integrated baseband channel filters to the baseband A/Dconverters which is contained in baseband chipset. Fig.3-2 shows RX path block diagram.

3.1.3 DC offset compensation

The transceiver IC(TRF6150) is based on direct-conversion architecture. This implies that aparasitic DC offset may appear at the output of the IQ demodulator. To reduce the static offset dueto components mismatch and LO self-mixing, the IC includes a hardware DC offset compensationcircuit on both I and Q base band paths. The transceiver IC uses a divider by 2 for LO generation inEGSM and a multiplier by 2 in DCS to minimize the DC offset generated by self mixing and the LOradiation. In addition, a quadrature demodulator gain mismatch calibration system is used to reducethe signal distortion.

3.2 SynthesizerThe TRF6150 includes two synthesizer parts. Two synthesizers consist of an IF synthesizer, whichis an integer-N synthesizer, and a RF synthesizer, which is a fractional-N synthesizer. The TRF6150is a transceiver IC suitable for GSM and DCS GPRS up to class 12 applications. So, synthesizersuse a number of techniques to improve lock time, making them well suited to GPRS.

The main fractional-N synthesizer (RF synthesizer), which includes a RF VCO with external tankcircuits, is necessary for both transmitting and receiving operation. The RF VCO works only whenthe transmitting operation is on. The main fractional-N synthesizer has frequency band from 1294MHz to 1356 MHz. Output frequency of the RF VCO is set by the factional number, prescaler andcounter. An buffer amplifier follows the RF VCO. The purpose of the buffer is to give reverseisolation and prevent any frequency pulling of the VCO when the transceiver is powered UP andDOWN.

A dual band external VCO, which uses the PLL block of the main fractional-N synthesizer, isnecessary for transmitting and receiving operation. The dual band means that it can support GSM,DCS frequency operation. For transmitting operation, the OPLL block of the TRF6150 directlymodulates the dual band external VCO with I and Q signals. For receiving operation, the externalVCO output frequency band is fr 90902 to 940MHz for DCS Rx and from 1850 to 1920MHz for GSMRx. The frequency of the signal from the external VCO is divided by 2 for GSM Rx and is doubled by2 for DCS Rx operation before entering into the direct conversion mixer.

The auxiliary integer-N synthesizer (IF synthesizer), which includes an IF VCO with external tankcircuits, is necessary for transmitting operation only. The IF VCO has a frequency band from 832MHz to 858 MHz. Output frequency of IF VCO is settled by prescaler and counter. The fractionalcounter in the RF synthesizer just differs from the IF synthesizer. The IF VCO is also followed by abuffer amplifier, which is to give reverse isolation and prevent any frequency pulling of the VCOwhen the transceiver is powered UP and DOWN.

A fixed reference frequency of 1.3MHz for Rx (or 2.6MHz for Tx) is generated by a reference dividerfrom the external applied 13 MHz crystal oscillator.

The phase frequency detector with charge pump provides programmable output current, whichcould drive the capability and the pulse width.

The counter and mode settings of the synthesizer in the TRF6150 are programmed via 3-wireinterface.

3.3 Transmitter The Transmitter part contains TRF6150 active parts, PAM, coupler, dual schottky diode and dualband VCO. The TRF6150 active parts consist of the vector modulator and offset phase-locked loopblock (OPLL) including down-converter, phase detector, and APC IC for power control. The VCOfeed the output frequencies into PAM and TRF6150 for Tx local frequency. The peak output powerof the PAM is controlled by means of a closed feedback loop. A dual band directional coupler isused to control the RF output from the PAM. The PAM outputs from the directional coupler pass tothe antenna connector via an integrated dual band antenna switch module.

3.3.1 Tx Modulator

The Tx I & Q signals from BB analog chipset are fed to the TRF6150 Tx modulator, where they aremodulated onto either a Tx of 880 MHz(for GSM-Tx) or 1710 MHz(for DCS-Tx) by the quadraturemixer inside the U604. The Tx LO signal(1294 – 1356 MHz, 426.4 MHz) is fed from the internalmain and aux.

VCO.

The modulator provides more than 40dBc of carrier and unwanted side-band rejection andproduces a GMSK modulated signal. The BB software is able to cancel out differential DC offsets inthe I/Q BB signals caused by imperfections in the D/A converters. The Tx-Modulator implements aquadrature modulator. The frequency input signal is split into two precise orthogonal carriers, whichare multiplied by the BB modulation signal IP/IN and QP/QN. It is used as reference signal for theOPLL.

Figure 3-6. TX IF Modulator and OPLL Circuit.

Page 18: LG W7020 Service Manual

3.3.2 OPLL

The down converter contained inside of the TRF6150 (U604) mixes the Tx RF frequency with theRF VCO signal from the ENFVZ4L07(U600) to generate a feedback signal at 414.4MHz for GSM,EGSM and DCS operation. The feedback signal passes to one port of the phase detector.

The GMSK reference signal from the Tx IF modulator passes via a second limiter to the otherinput port of the phase detector. The phase detector generates an error current proportional to thephase difference between the feedback signal from the down-converter and the `reference’ signalfrom the Tx IF modulator. The error current is filtered by a second order low-pass filter to generatean output voltage, which depends on the GMSK modulation and the desired channel frequency.This voltage controls the transmit VCO such that the VCO output signal, centered on the correct RFchannel is frequency modulated with the original GMSK data.

The center frequency of the transmit VCO is offset from the RF VCO frequency by 414.4MHz forGSM ,EGSM and DCS operation.

3.3.3 Power Amplifier

The PF08122B (U601) is Dual band power amplifier for EGSM (880 to 915 MHz) and DCS (1710 to1785 MHz). The efficiency of module is the 55% at 35 dBm for E-GSM and the 50% at 32.5 dBm forDCS for 3.5 V nominal battery use.

This module should be operated under the GSM burst pulse. To avoid permanent degradation, CWoperation should not be applied. To avoid the oscillation at no input power, before the input is cutoff, the control voltage Vapc should be control to less than 0.5 V. We have to improve thermalresistance, the through holes should be layouted as many as possible on PCB under the module.And to get good stability, all the GND terminals and the metal cap should be soldered to groundplane of PCB.

3.3.4 PA Circuit and Control

The power amplifier control circuit ensures that the RF signal is regulated to the required limits ofoperation. RF power is controlled by driving the power control pins of power amplifier and sensing.The resultant RF output power via a directional coupler (N600). The RF sense voltage is peakdetected using an schottky diode of BAT15-099(D600). This detected voltage is compared to theDAC voltage in the TRF6150 to control the output power.

An internal input signal (PA_LEVEL) from CALYPSO, digital BB chipset, (U200) is applied to theAPC IC in TRF6150 during the PA_ON mode and a directional coupler near the antenna feeds aportion of the RF output signal back to the APC IC and peak detector converts this signal to a lowfrequency feedback signal that balances the amplifier when this signal equal to the RAMP inputsignal level.

3.4 13 MHz ClockThe 13 MHz clock (VC-TCXO-208C) consists of a TCXO (Temperature Compensated CrystalOscillator), which oscillates at a frequency of 13 MHz.The 13MHz clock is used within the Synthesizer block of the TRF6150, BB Analog chip-set(NAUCICA_CS), and Digital (CALYPSO). The inverter IC, SN74AHC1GU04 buffer the output toNAUCICA_CS and CALYPSO.

3.5 Power Supplies and Control SignalsThree Regulators are integrated in the TRF6150 to provide DC power to the RF blocks (RegulatorR1, R2 R3). The Regulator R1 is used to provide DC power to the receiver, the transmitter and thePA control loop of the TRF6150. The Regulator R2 is used to provide DC power to the DC offsetcompensation circuit, the auxiliary synthesizer, the main synthesizer and VCOs. The Regulator R3is used for the external Rx/Tx VCO.

3.7.2 Audio Signal Processing & Interface

Audio signal processing is divided Uplink path and downlink path..

The uplink path amplifies the audio signal from MIC and converts this analog signal to digital signaland then transmit it to DBB Chip. This transmitted signal is reformed to fit in GSM Frame format anddelivered to RF Chip. MICBIAS is 2.5Vlevel.

The downlink path amplifies the signal from DBB chip and outputs it to Receiver(or Speaker).

Figure 3-13. Audio Interface Block Diagram

3.7.3 Baseband Codec(BBC)

Baseband codec is composed of baseband uplink path(BUL) and baseband downlink path(BDL).

BUL makes GMSK(Gaussian Minimum Shift Keying) modulated signal which has In-phase(I) com-ponent and quadrature(Q) component with burst data from DBB. This modulated signal istransmitted through RF section via air.

BDL process is opposite procedure of BUL. Namely, it performs GMSK demodulation with inputanalog I&Q signal from RF section, and then transmit it to DSP of DBB chip with 270KHz data ratethrough BSP.

4.2.1 Overview

All tuning operations of the phone are carried out using the service software. The service softwareturns the phone into the locals mode, in which the phone can be outwardly controlled via the testJig.The calibration values of the phone reside on the Flash. The contents of the Flash can be read bythe service software and saved as a file. This is advisable when there is need to retain thatinformation, e.g. in view of replacement of the circuit. The program also enables writing the defaultparameters on the Flash, in which case all calibration steps should be carried out. The servicesoftware can’t control the equipment, so only manual calibration process is possible.

4.2.4 Calibration Steps

A. RX CalibrationIn order for the RSSI measurements to be within the GSM specifications, some calibration isnecessary. Also, due to AGC implementation, some AGC specific constants need calibration. Intotal, three calibrations are required per receive band, AGC calibration, channel compensationand temperature compensation. Of these, temperature compensation is not needed inreplacement of the circuit. In AGC calibration the reference power fed into the phone viapermanent antenna connector is –74dBm. In channel compensation, the channel numbers in Rxband are;

E-GSM band : 0, 40, 124, 975, and 1023.

DCS band : 512, 574, 636, 700, 760, 822 and 885.

- Procedure

a) Initialize phone by clicking Initialize button.

b) Set the GSM test equipment CW mode and BCH and TCH of GSM test equipment ‘0’, samewith phone.

c) Set the power of GSM test equipment ‘–74dBm’.

d) Click the PM Start button, then the value, received power by phone, is displayed in PMmeasurement window at service software.

e) Change the BCH and TCH of phone by clicking the Number button and set the channel(BCH & TCH) of equipment to be same.

f) Click the PM Start button.

g) Repeat above procedure until the displayed number in Power Measurement window is 12.

h) Click the Calculate button, then the service software calculate the channel compensationparameters.

i) Saving updated calibration data into phone by clicking Calib Saving button.

NOTE

If the calibration does not done for all channels, 5 channels for EGSM900 and 7 channels forDCS1800, the service software reports, “Please execute after measuring the PM”.

B. TX CalibrationIn order for the Tx power to be within the GSM specifications for each Tx level, some calibrationis necessary. In total, four calibrations are required per transmit band, power calibration, channelcompensation, temperature compensation and low voltage compensation. Of these, temperaturecompensation and low voltage compensation are not needed in replacement of the circuit andchannel compensation is not needed because the transmit power is in GSM specification withenough margin.In power compensation, the channel numbers used in Tx band are;

E-GSM band : 62.

DCS band : 699.

And the target powers in dBm for each power level are;

7.1 Testing Set-up

7.1.1 Received RF Level and Checks

This section shows the typical RF levels expected throughout the receiver path. A block diagramshowing the locations of the RF measurement points and levels is shown in Figure 7-3.

Receiver Testing Set-upTo check the receiver the following conditions have to be set:

1. On a signal generator or a GSM/DCS test box, output a CW signal of amplitude = -60 dBm ateither: 947.4 MHz (CH62) when testing the GSM RX path or 1842. 6 MHz (CH699) when testingthe DCS RX path.

2. Set the DC power supply to 4.0 V.

Note: All RF values shown are only intended as a guide figure and may differ from readings takenwith other test equipment and leads. Lead and connector losses should always be taken intoaccount when performing such RF measurements.

Testing ReceiverUsing a suitable high frequency probe measure the RF levels at the relevant points shown in Figure 7-2. and compares your measurements with those shown in the diagram. If there are anymajor difference between the readings taken and those indicated then further investigation of thatparticular point will be required. It will also be necessary to ensure that all the following powersupplies and signals are present which control this part of the receiver circuit:

1. The Control Signal of Antenna switch (see Figure 7-9,10,11 )

2. Vreg 1,2,3 (see Figure 7-7 )

3. 2V85_VCTCXO (see Figure 7-8)

7.1.2 Transmitted RF Level and Checks

This section shows the typical RF levels expected throughout the transmitter path. A block diagramshowing the locations of the RF measurement points and levels is shown in Figure 7-5.

Transmitter Testing Set-upTo check the transmitter the following conditions have to be set:

1. Configure the testing equipments as Figure equipment setup.

2. Set the GSM/DCS test equipment to be stand-alone mode (asynchronous mode).

3. Set the BCH and TCH ARFCN ‘62’ for EGSM900 or ‘700’ for DCS1800 on GSM/DCS testequipment.

4. Set the DC power supply 4.0volts.

5. Initialize target on service software.

6. Set TCH and BCH value to be same with GSM/DCS test equipment on service software.

7. Select GSM or DCS mode on service software.

8. Set DAC ‘600’ for EGSM900 or ‘700’ for DCS1800 on service software.

9. Click Test.

Note: All RF values shown are only intended as a guide figure and may differ from readings takenwith other test equipment and leads. Lead and connector losses should always be taken intoaccount when performing such RF measurements.

Testing TransmitterUsing a suitable high frequency probe measure the RF levels at the relevant points shown in Fig. 7-4 and compare your measurements with those shown in the diagram. If there are any majordifference between the readings taken and those indicated then further investigation of thatparticular point will be required. It will also be necessary to ensure that all the following powersupplies and signals are present which control this part of the transmitter circuit:

1. The Control Signal of Antenna Switch(see Figure 7-9, 10, 11)

2. Vreg 1,2,3 (see Figure. 7-7)
