1. INTRODUCTION

1.1 Purpose

This manual provides the information necessary to repair, calibration, description and download the

features of the KS360 Series.

1.2 Regulatory Information

A. Security

Toll fraud, the unauthorized use of telecommunications system by an unauthorized part (for example,

persons other than your company’s employees, agents, subcontractors, or person working on your

company’s behalf) can result in substantial additional charges you’re your telecommunications

services. System users are responsible for the security of own system. There are may be risks of toll

fraud associated with your telecommunications system. System users are responsible for

programming and configuring the equipment to prevent unauthorized use. LGE does not warrant that

this product is immune from the above case but will prevent unauthorized use of common-carrier

telecommunication service of facilities accessed through or connected to it. LGE will not be

responsible for any charges that result from such unauthorized use.

B. Incidence of Harm

If a telephone company determines that the equipment provided to customer is faulty and possibly

causing harm or interruption in service to the telephone network, it should disconnect telephone

service until repair can be done. A telephone company may temporarily disconnect service as long as

repair is not done.

C. Changes in Service

A local telephone company may make changes in its communications facilities or procedure. If these

changes could reasonably be expected to affect the use of the KS360 Series or compatibility with the

network, the telephone company is required to give advanced written notice to the user, allowing the

user to take appropriate steps to maintain telephone service.

D. Maintenance Limitations

Maintenance limitations on the KS360 Series must be performed only at the LGE or its authorized

agents. The user may not make any changes and/or repairs expect as specifically noted in this

manual. Therefore, note that unauthorized alternations or repair may affect the regulatory status of the

system and may void any remaining warranty.

3.12 LCD back light illumination

MAX8630W is a charge pump designed to support PWM control mode. And MAX8630W supports 5

white LEDs. The MAX8630W is capable of driving up to 5 LEDs at a total of 100mA(MAX8630W

100mA).

The current sinks may be operated individually or in parallel for driving higher current LEDs. To

maximize power efficiency, the charge pump operates in 1X, 1.5X, or 2X mode, where the mode of

operation is automatically selected by comparing the forward voltage of each LED with the input

voltage.

3.21 Receiver part

Figure 25. Receiver Block Diagram of S-GOLDradio

The constant gain direct conversion receiver contains all active circuits for a complete receiver chain

for GSM/GPRS/EDGE (see Figure 25). The GSM850/900/DCS1800/ PCS1900 LNAs with balanced

inputs are fully integrated. No inter-stage filtering is needed. The orthogonal LO signals are generated

by a divider-by-four for GSM850/900 band and a divider-by-two for the DCS1800/PCS1900 band.

Down conversion to baseband domain is performed by low/high band quadrature direct down

conversion mixers. The baseband chain contains a LNB (low noise buffer), channel filter, output buffer

and DC-offset compensation. The 3rd order low pass filter is fully integrated and provides sufficient

suppression of blocking signals as well as adjacent channel interferers and avoids anti-aliasing

through the baseband ADC. The receive path is fully differential to suppress on-chip interferences.

Several gain steps are implemented to cope with the dynamic range of the input signals. Depending

on the baseband ADC dynamic range, single- or multiple gain step switching schemes are applicable.

Furthermore an automatic DC-offset compensation can be used (depending on the gain setting) to

reduce the DC-offset at baseband-output. A programmable gain correction can be applied to correct

for front end- and receiver gain tolerances.

3. TECHNICAL BRIEF

3.22 Transmitter part

The GMSK transmitter supports power class 4 for GSM850 and GSM900 as well as power class 1 for

DCS1800 and PCS1900. The digital transmitter architecture is based on a very low power fractional-N

Sigma-Delta synthesizer without any external components (see Figure26). The analog I/Q modulation

data from the baseband is converted to digital, filtered and transformed to polar coordinates. The

phase/frequency signal is further on processed by the Sigma-Delta modulation loop. The output of its

associated VCO is divided by four or two, respectively, and connected via an output buffer to the

appropriate single ended output pin. This configuration ensures minimum noise level. The 8PSK

transmitter supports power class E2 for GSM850 and GSM900 as well as for DCS1800 and PCS1900.

The digital transmitter architecture is based on a polar modulation architecture, where the analog

modulation data (rectangular I/Q coordinates) is converted to digital data stream and is subsequently

transformed to polar coordinates by means of a CORDIC algorithm. The resulting amplitude

information is fed into a digital multiplier for power ramping and level control. The ready processed

amplitude signal is applied to a DAC followed by a low pass filter which reconstructs the analog

amplitude information.

The phase signal from the CORDIC is applied to the Sigma-Delta fractional-N modulation loop. The

divided output of its associated VCO is fed to a highly linear amplitude modulator, recombining

amplitude and phase information. The output of the amplitude modulator is connected to a single

ended output RF PGA for digitally setting the wanted transmit power. The PA interface of SMARTi-PM

supports direct control of standard dual mode power amplifiers (PA’s) which usually have a power

control input VAPC and an optional bias control pin VBIAS for efficiency enhancement. In GMSK

mode, the PA is in saturated high efficiency mode and is controlled via its VAPC pin directly by the

baseband ramping DAC.

In this way both up- / down-ramping and output power level are set. In 8PSK mode, the ramping

functionality is assured by an on-chip ramping generator, whereas output power is controlled by the

PGA’s as described above.

3. TECHNICAL BRIEF

Figure 26. Transmitter Architecture Block Diagram

3.23 RF synthesizer

The transceiver contains a fractional-N sigma-delta synthesizer for the frequency synthesis in the RX

operation mode. For TX operation mode the fractional-N sigma-delta synthesizer is used as Sigma-

Delta modulation loop to process the phase/frequency signal. The 26MHz reference signal is provided

by the internal crystal oscillator. This frequency serves as comparison frequency of the phase detector

and as clock frequency for all digital circuitry.The divider in the feedback path of the synthesizer is

carried out as a multi-modulus divider (MMD). The loop filter is fully integrated and the loop bandwidth

is about 100 kHz to allow the transfer of the phase modulation. The loop bandwidth is automatically

adjusted prior to each slot (OLGA ). To overcome the statistical spread of the loop filter element values

an automatic loop filter adjustment (ALFA) is performed before each synthesizer startup.

The fully integrated quad-band VCO is designed for the four GSM bands (850, 900, 1800, 1900 MHz)

and operates at double or four times transmit or receive frequency. To cover the wide frequency range

the VCO is automatically aligned by a binary automatic band selection (BABS) before each

synthesizer startup.

3. TECHNICAL BRIEF

3.24 DCXO

The transceiver contains a fully integrated 26MHz digitally controlled crystal oscillator (DCXO) with

three outputs for the system clock, one output for the GSM baseband and two additional for other

subsystems (GPS, Bluetooth, etc.). The only external part of the oscillator is the crystal itself. The

overall pulling range of the DCXO consists of eight subranges. The subrange closest to the ‘0ppm’ at

the middle AFC-value is selected during the calibration process in the mobile’s production and is used

for the rest of the lifetime. The frequency tuning is performed along the selected subrange by

programming the frequency control word (XO_TUNE) via the three wire bus (“3Wbus”).

3.25 Front End Module control

Implemented in the Transceiver are two outputs for direct control of front end modules with two logic

input pins to select RX- and TX-mode as well as low- and high band operation.
