CHAPTER 3. Circuit Description

1. RF Transmit/Receive Part 1.1 Overview

The Tx and Rx part employs the Direct-Conversion system. The Tx and Rx frequencies are respectively

824.04~848.97 and 869.04~893.97 for cellular and 1850~1910 and 1930~1990 for PCS. The block diagram is

shown in [Figure 1-1]. RF signals received through the antenna are seperated by the Quintplexer.

RF Signal fed into the low noise amplifier (LNA) through the Quintplexer. Then, they are fed into RFR6000. In

RFR6000, the RF signal is changed into baseband signal directly. Then, this signal is changed into digital signal

by the analog to digital converter (ADC, A/D Converter), and the digital circuit part of the MSM(Mobile Station

Modem) 6100 processes the data from ADC. The digital processing part is a demodulator.

In the case of transmission, RFT6100 receives OQPSK-modulated anlaog signal from the MSM6100.

The RFT6100 connects directly with MSM6100 using an analog baseband interface. In RFT6100, the baseband

quadrature signals are upconverted to the Cellular or PCS frequency bands and amplified to provide signal drive

capability to the power amp.

After that, the RF signal is amplified by the Power Amp in order to have enough power for radiation. Finally,

the RF signal is sent out to the cell site via the antenna after going through the Quintplexer.

1.2 Description of Receive Part Circuit 1.2.1 Quintplexer (U101)

The Quintplexer consists of the Rx bandpass filter (BPF), the Tx BPF and the GPS filter(BPF) which has

the function of separating Tx, Rx and GPS signals in the full Triplex system for using the common antenna. The

Tx part BPF is used to suppress noises and spurious out of the Tx frequency band. The Rx BPF is used to

receive only Rx signal coming from the antenna, which is usually called preselector. It’s main function is to

limit the bandwidth of spectrum reaching the LNA and mixer, attenuate receiver spurious response and suppress

local oscillator energy. As a result frequency sensitivity and selectivity of mobile phone increase. The

1.2.2 LNAs (U107)

The RFL6000 has cellular and PCS LNAs, respectively. The characteristics of Low Noise Amplifier (LNA)

are low noise figure, high gain, high intercept point and high reverse isolation. The frequency selectivity

characteristic of mobile phone is mostly determined by LNA.

The specification of LX260 LNAs are described below:

1.2.3 Down-converter Mixers and GPS LNA (U111)

The RFR6000 device performs signal down-conversion for Cellular, PCS and GPS tri-band applications. It

contains all the circuitry (with the exception of external filters) needed to support conversion of received RF

signals to baseband signals. The three downconverting Mixers (Cellular, PCS and GPS), and an LO Buffer

Amplifier to buffer the RF VCO to the RF Transmit Upconverter. The GPS LNA & mixers offer the most

advanced and integrated CDMA Rx solution designed to meet cascaded Noise Figure (NF) and Third-order

Intercept Point (IIP3) requirements of IS-98C and J-STD-018 specifications for Sensitivity, Two-Tone

Intermodulation, and Single-tone Desense.

Operation modes and band selection are specially controlled from the Mobile Station Modem MSM6100.

The specification of LX260 Mixers are described below:

-22-

The main function of Rx RF SAW filter is to attenuate mobile phone spurious frequency, attenuate noise

amplified by the LNA and suppress second harmonic originating in the LNA.

1.3 Description of Transmit Part Circuit 1.3.1 RFT6100 (U112)

The RFT6100 baseband-to-RF Transmit Processor performs all Tx signal-processing functions required

between digital baseband and the Power Amplifier Modulator (PAM). The baseband quadrature signals are

upconverted to the Cellular or PCS frequency bands and amplified to provide signal drive capability to the PAM.

The RFT6100 includes an mixers for up-converting analog baseband to RF, a programmable PLL for generating

Tx and Rx LO frequency, cellular and PCS driver amplifiers and Tx power control through an 85 dB VGA. As

added benefit, the single sideband upconversion eliminates the need for a band pass filter normally required

between the upconverter and driver amplifier.

I, I/, Q and Q/ signals proceed from the MSM6100 to RFT6100 are analog signal. In CDMA mode, These

signals are modulated by Offset Quadrature Phase Shift King (OQPSK). I and Q are 90 deg. out of phase, and I

and I/ are 180 deg. The mixers in RFT6100 converts baseband signals into RF signals. After passing through

the upconverters, RF signal is inputted into the Power AMP.

1.3.2 Power Amplifier(U108,109)

The power amplifier that can be used in the PCS and CDMA mode has linear amplification capability and

high efficiency. For higher efficiency, it is made up of one MMIC (Monolithic Microwave Integrated Circuit)

for which RF input terminal and internal interface circuit are integrated onto one IC after going through the




AlGaAs/GaAs HBT (heterojunction bipolar transistor) process. The module of power amplifier is made up of an

output end interface circuit including this MMIC. The maximum power that can be inputted through the input

terminal is +17dBm and conversion gain is about 28dB. RF transmit signals that have been amplified through

the power amplifier are sent to the Quintplexer.

1.4 Description of Frequency Synthesizer Circuit 1.4.1 Voltage Control Temperature Compensation Crystal Oscillator (VCTCXO, X100)

The temperature variation of mobile phone can be compensated by VCTCXO. The reference frequency of a

mobile phone is 19.2 MHz. The receiver frequency tuning signals called TRK_LO_ADJ from MSM as 0.5

V~2.5 V DC via R and C filter in order to generate the reference frequency of 19.2 MHz and input it into the

frequency synthesizer. Frequency stability depending on temperature is ±1.5 ppm.

1.4.2 Voltage Controlled Oscillator (VCO, U110)

The external VCO signal is processed by the LO generation and distribution circuits in RFR6000 to create the

PCS and Cellular quadrature downconverter’s LO signals. Likewise, the internal VCO signal of RFR6000 is

processed to create the GPS quadrature downconverter’s LO signal. In all cases, the LO signals applied at the

mixer ports are at the frequency different than the VCO frequency. This assures that the VCO frequency is

different than the RF frequency, an important consideration for Zero-IF processing. The VCO frequency used

are 1715.56~1768.89 MHz for PCS and 1738.08~1787.94 MHz for cellular.

2. Digital/Voice Processing Part 2.1 Overview

2.2 Configuration 2.2.1 Keypad/LCD and Receptacle Part

This is used to transmit keypad signals to MSM6100. It is made up of a keypad backlight part that illuminates




-24-

the keypad, LCD part that displays the operation status onto the screen, and a receptacle that receives and sends

out voice and data with external sources.

2.2.2 Voice Processing Part

The voice processing part is made up of an audio codec used to convert MIC signals into digital voice signals

and digital voice signals into analog voice signals, amplifying part for amplifying the voice signals and sending

them to the ear piece, amplifying part that amplifies ringer signals coming out from MSM6100, and amplifying

part that amplifies signals coming out from MIC and transferring them to the audio processor.

2.2.3 MSM (Mobile Station Modem) 6100 Part

The memory part is made up of a NAND Flash memory, SDRAM for storing data.

2.2.5 Power Supply Part

The power supply part is made up of circuits for generating various types of power, used for the digital/voice

processing part.

2.3 Circuit Description 2.3.1 Keypad/LCD and Receptacle Part

Once the keypad is pressed, the key signals are sent out to MSM6100 for processing. In addition, when the

key is pressed, the keypad/LCD lights up through the use of 20 LEDs. The terminal status and operation are

displayed on the screen for the user with the characters and icons on the LCD. Moreover, it exchanges audio signals and data with external sources through the receptacle, and then receives

power from the battery or external batteries.

2.3.2 Audio Processing Part




MIC signals are amplified through OP AMP, inputted into the audio codec(included in MSM6100) and

converted into digital signals. Oppositely, digital audio signals are converted into analog signals after going

through the audio codec. These signals are amplified at the audio amplifier and transmitted to the ear-piece. The

signals from MSM6100 activate the ringer by using signals generated in the timer in MSM6100.

2.3.3 MSM Part

MSM6100 is the core element of CDMA system terminal that includes ARM9TDMI microprocessor core. It

supports both CDMA and Digital FM, operating in both the cellular and PCS spectrums. The subsystems within

the MSM6100 include a CDMA processor, a DFM processor, a multi-standard Vocoder, an integrated CODEC

with earpiece and microphone amplifiers, general-purpose ADC for subsytem monitoring, an ARM9TDMI

microprocessor, and both Universal Serial Bus(USB) and an RS-232 serial interfaces supporting forward and

reverse link data communications of 307.2 Kbps simultaneously. And it also contains complete digital

modulation and demodulation systems for both CDMA and AMPS cellular standards, as specified in

IS-95-A/B/C.

In MSM, coded symbols are interleaved in order to cope with multi-path fading. Each data channel is

scrambled by the long code PN sequence of the user in order to ensure the confidentiality of calls. Moreover,

binary quadrature codes are used based on walsh functions in order to discern each channel. Data created thus

are 4-phase modulated by one pair of Pilot PN code and they are used to create I and Q data.

When received, I and Q data are demodulated into symbols by the demodulator, and then de-interleaved in

reverse to the case of transmission. Then, the errors of data received from viterbi decoder are detected and

corrected. They are voice-decoded at the vocoder in order to output digital voice data.

[Figure 2-2] Block Diagram of Digital/Voice Processing Part 2.3.4 Memory Part

MCP contents 512 Mbits NAND flash memory and 512 Mbits SDRAM. In the Flash Memory part of MCP is

programs used for terminal operation. The programs can be changed through down loading after the assembling

of terminals. On the SDRAM data generated during the terminal operation are stored temporarily.

2.3.5 Power Supply Part

When the battery voltage (+4.0V) is fed and the PWR key of keypad is pressed, the power-up circuitry in PM

(power management) IC (U400) is activated by the PWR_ON_SW signal, and then the LDO regulators

embedded in PMIC for MSM) are operated and +1.86V_MSMC, +2.6V_MSMP and +2.6V_MSMA are

generated.

The Rx part regulator (+2.9V_RX) is operated by the control signal of SLEEP/ from MSM6100.

The Tx part regulator (+2.9V_TX) is operated by the I2C control signal from MSM6100. 2.3.6 Logic Part

The logic part consists of internal CPU of MSM, RAM, MCP. The MSM6100 receives TCXO (=19.2MHz)

from X100 and controls the phone in CDMA modes. The major components are as follows:

CPU

The ARM9TDMI microprocessor includes a 3 stage pipelined RISC architecture, both 32-bit ARM and 16-bit

THUMB instruction sets, a 32-bit address bus, and a 32-bit internal data bus. It has a high performance and

low power consumption.

MCP

Flash ROM is used to store the terminal’s program. Using the down-loading program, the program can be

changed even after the terminal is fully assembled.

SDRAM is used to store the internal flag information, call processing data, and timer data.

KEYPAD

For key recognition, key matrix is setup using KYPD[1][3][5][7][9][11][13][15][17][19] signal from MSM.

20 LEDs and backlight circuitry are included in the keypad for easy operation in the dark.

LCD MODULE




LCD module contains a controller which will display the information onto the LCD by 16-bit data from the

MSM6100. It is also supplied stable 2.8V_LCD by regulator in U400 for fine view angle and LCD reflects to

improve the display efficiency. 3 LEDs are used to display LCD backlight.

IMPORTANTRead This Information Before Using Your Hand-Held Portable Cellular TelephoneFirst introduction in 1984, the hand-held portable Cellular telephone is one of the most exciting and innovative electronic products ever developed.With it you can stay in contact with your office, your home, emergency service, and others. For the safe and efficient operation of your phone, observe these guidelines.Your Cellular phone is a radio transmitter and receiver. When it is ON, it receives and also sends out radio frequency (RF) energy. The phone operates in the frequency range of 824 MHz to 894 MHz and employs commonly used frequency modulation (FM) techniques. When you use your phone, the Cellular system handling your calls controls the power level at which your phone transmits. The power level can range from 0.006 of a watt to .6 of a watt.

Exposure to Radio Frequency EnergyIn 1991 the Institute of Electrical and Electronics Engineers (IEEE), and in 1992 the American National Standards Institute (ANSI) updates the 1982 ANSI Standard for safety levels with respect to human exposure to RF energy. Over 120 scientists, engineers, and physicians from universities, government health agencies, and industry, after reviewing the available boy of research, developed this updated Standard. In March, 1993, the US Federal Communications Commission (FCC) proposed the adoption of this updated Standard.The design of your phone complies with this updated Standard. Of course, if you want to limit RF exposure even further than the updated ANSI Standard, you may choose to control the duration of your calls and operation your phone in the most power efficient manner.

Efficient Phone OperationFor your phone to operate at the lowest power level, consistent with satisfactory call quality, please observe the following guidelines:If your phone has an extendable antenna, extend it fully. Some models allow you to place a call with the antenna retracted. However, your phone operates more efficiently with the antenna fully extended.Hold the phone as you would any other telephone. While speaking directly into the mouthpiece, position the antenna up and over your shoulder.Do not hold the antenna when the phone is “IN USE”. Holding the antenna affects call quality and may cause the phone to operated at a higher power level than needed.

Antenna Care and ReplacementDo not use the phone with a damaged antenna. If a damaged antenna comes into contact with skin, a minor bum may result. Replace a damaged antenna immediately. Consult your manual to see if you may change your antenna yourself. If so, use only a manufacture approves antenna. Otherwise, take your phone to a qualifies service center for repair.Use only the supplied or approved antenna. Non-approved antennas, modifications, or attachments, could impair call quality, damage the phone, and violate FCC regulations.

CHAPTER 5. SafetyCHAPTER 5. Safety

-120-




DrivingCheck the laws and regulations on the use of Cellular telephones in the areas where you drive. Always obey them. Also, when using your phone while driving, please:Give full attention to the driving. Use hands-free operation, if available, and pull off the road and park before making or answering a call if driving conditions require.

Electronic DevicesMost modem electronic equipment is shielded from RF energy. However, RF energy from Cellular telephones may affect inadequately shielded electronic equipment.RF energy may effect improperly installed or inadequately shielded electronic operating and entertainment system in motor vehicles. Check with the manufacturer or its representative to determine if these systems are adequately shielded from external RF energy. You should check with the manufacturer of any equipment that has been added to your vehicle.Consult the manufacturer of any personal medical devices (such as pacemakers, hearing aids, etc.) to determine if they are adequately shielded from external RF energy.Turn your phone OFF in health care facilities. When any regulations posted in the areas instruct you to do so. Hospitals or health care facilities may be using equipment that could be sensitive to external RF energy.

AircraftTurn your phone OFF before boarding any aircraft.Use it on the ground only with crew permission. Do not use it in the air.To prevent possible interference with aircraft systems, US Federal Aviation Administration (FAA) regulations require you to have permission from a crew member to use your phone while the plane is on the ground. Using your phone while the plane is in the air.

ChildrenDo not allow children to play with your phone. It is not a toy. Children could hurt themselves or others (by poking themselves or others in the eye with the antenna, for example). Children also could damage the phone, or make calls that increase your telephone bills.

Blasting AreasTo avoid interfering with blasting operations, turn you unit OFF when in a “blasting area” or in areas posted “Turn off two-way radio”. Construction crews often use remote control RF devices to set off explosives.

Potentially Explosive AtmospheresTurn your phone OFF when in any area with a potentially explosive atmosphere. It is rare, but your phone or accessories could generate sparks. Sparks in such area could cause an explosion or fire resulting in bodily injury or even death.Areas with a potentially explosive atmosphere are often, but not always, clearly marked. They include fueling areas such as gas station; below deck on boats; fuel or chemical transfer or storage facilities; areas where the air contains chemical or particles, such as grain, dust, or metal powders; and any other area where you would normally be advised to turn off your vehicle engine.

-121-




Do not transport or store flammable gas, liquid, or explosives in the compartment of your vehicle which contains your phone or accessories.Vehicles using liquefied petroleum gas (such as propane or butane) must compl7y with the National Fire Protection Standard (NFPA-58). For a copy of this standard, contact the National Fire Protection Association, One Battery march Park, Quincy, MA 02269, Attn: Publication Sales Division.Rule of Thumb: Using common sense at all times when handling, installing or using the phone. Any questions should be directed to you nearest Service Center or authorized service technician or electrician.
