4. Technical Description
4.1 Overview
This product consists with 3 parts, which are RF, logic, and UI interface. The block diagram is shown in
Figure 4.1. This product employs the Super-Heterodyne method for wireless communication and the Tx
and Rx frequencies are 824.04~848.97MHz and 869.04~893.9MHz respectively. RF signals received
through the antenna are fed into the low noise amplifier (Receiver MMIC/ LNA, U106) through the duplexer
(F100). Then, they are combined with the signals of local oscillator (VCO, U102) at the down conversion
mixer (Receiver MMIC, U106) in order to create the intermediate frequency (IF). The IF signal is fed into
RX_BBA(U109) through band-pass filter (BPF, U108),. In RX_BBA(U109), the IF signal is changed into
base-band signal. Then, this signal is changed into the digital signal by the analog to digital converter
(ADC, A/D Converter), and the digital circuit part of the MSM(U125) processes the data from ADC. In the
case of transmission, The TX_BBA(U112) receives digital signal from the MSM(U125). In MSM(U125), the
digital signal is changed into analog signal by the digital to analog converter (DAC, D/A Converter), and
then the quadrature signals of base-band are up-converted to the IF frequency bands in TX_BBA(U112).
The Tx AGC in TX_BBA(U112) is designed to be gain-controlled from 85dB dynamic range. In
TX_BBA(U112), the Tx IF frequency mixed with RF local frequency is created Tx RF frequency. After that,
the Power amplifier module(U110) amplifies the RF signal 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 duplexer (F110).

4.2 RF part Description
The RF part consists of power part, synthesizing part, transmission and reception part.
4.2.1 Description of Frequency Synthesizer Circuit
The UHF band frequency synthesizer is composed of an indirect frequency synthesizer, Phase Locked
Loop (PLL IC, U2), VCO(U102) with the center frequency of 966.88MHz for CDMA mode and Loop Filter.
PLL IC(U2)’s phase detector compares the reference clock frequency (19.68MHz, TCXO(U104) clock)
divided down to 30kHz by the reference divider with a signal divided by the PLL IC(U2) main divider from
the VCO(U102), and generates a local oscillation signals with zero phase difference. These local oscillation
signals are used for Tx and Rx. The other PLL synthesizer controls Tx IF frequency and is implemented on
the TX_BBA(U112). The Tx phase detector receives Tx IF local oscillation signal(260.76MHz) within the
TX_BBA(U112). In Rx IF synthesizer, UHF PLL synthesizer support dual frequencies. Thus
RX_BBA(U109) use UHF PLL to generate the Rx IF frequency(170.76MHz).
Voltage Control Temperature Compensation Crystal Oscillator (VCTCXO, U104)
The temperature variation of reference frequency in a mobile phone can be compensated by
VCTCXO(U104). The reference frequency of a mobile phone is operated stably from –30 to +60 °C. The
VCTCXO(U104) receives frequency tuning signals called TRK_LO_ADJ from MSM(U125) through low-
pass filter in order to generate the reference frequency of 19.68MHz and is used for system main clock.
Frequency stability depending on temperature is within ±1.5 ppm.
RF Frequency Synthesizer
The RF PLL is consisted of the dual mode PLL IC(U2), loop filter, VCO(U102) and VCTCXO(U104). It
generates the RF local frequency of 954.38 ~ 979.38 MHz.
RX IF Frequency Synthesizer
The Rx IF PLL is consisted of the dual mode PLL IC(U2), Rx IF VCO included in the RX_BBA(U109),
loop filter and VCTCXO(U104). The Rx IF VCO included in the RX_BBA(U109) oscillates twice Rx IF
frequency as 170.76MHz and then generates the RX IF frequency of 85.38MHz by dividing the Rx IF
VCO output frequency by two.
TX IF Frequency Synthesizer
The Tx IF PLL Loop is consisted of the Tx IF PLL synthesizer, VCO(U108) that are internally installed in
the TX_BBA(U112), loop filter and VCTCXO(U104). The Tx IF VCO included the TX_BBA(U112)
generates Tx IF local frequency of 260.76MHz and then generates the Tx IF frequency of 130.38MH by

4.2.2 Description of Rx Part Circuit
Cellular Receiver covers the RF frequency band of 869 ~ 894 MHz and the IF frequency of 85.38MHz.
The RF signal received is sent out to the Receiver MMIC/ LNA(U106) via a duplexer(F100) for
amplification and then, is sent out to the Receiver MMIC/ Down mixer(U106) through Rx RF SAW
filter(U107). Here, the RF signal is mixed with the VCO(U102) signal of 954.38 MHz ~979.38 MHz. IF
signal converted by the Receiver MMIC/ Down mixer(U106) are sent out to IF SAW Filter(U108), which
have a role to filter a wanted frequency. The signal that has passed the IF SAW filter(U108) is fed into
AGC AMP that is controlled by the power density modulation (PDM) signal of the MSM(U125) based on
the strength of received signal. This AGC AMP is tuned into the level corresponding to the input window of
the base band analog processor (RX_BBA, U109). The AGC AMP controls Rx power level within 85dB
dynamic range. The signal entered to RX_BBA(U109) is converted again to 1.2288 MHz base band signal.
To do second frequency conversion, the frequency synthesizer in RX_BBA (U109) generates frequency of
170.76MHz and these signals are divided by two in order to use the Rx IF LO signal. These signals are
used to convert RX IF signals to I/Q base band signal. I and Q base-band signals are respectively sent out
to the analog digital converter via a low pass filter.
Duplexer (F100)
The duplexer(F100) consists of the Rx bandpass filter (BPF) and the Tx BPF which have the function of
separating Tx and Rx signals in the full duplex system for using the common antenna. The Tx 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. Its main function limits the bandwidth
of spectrum reaching the Receiver MMIC/ LNA(U106) and attenuates receiver spurious response. As a
result, the frequency sensitivity and selectivity of mobile phone increase.
Receiver MMIC/ LNA (U106)/ Down Mixer (U106)
- LNA : The characteristics of Low Noise Amplifier (LNA, U106) 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(U106).
- The Down Mixer(U106) performs frequency translation by multiplying two signals. The
downconversion mixer employed in the Rx path has two distinctly different inputs, which are RF and
Local Oscillator (LO) signal. The RF signal is downconverted to IF signal by the local oscillator.
Rx RF SAW Filter (U107)
The main function of Rx RF SAW filter(U107) is to attenuate mobile phone spurious frequency, attenuate
direct IF frequency pick up, attenuate noise at the image frequency originating in or amplified by the
LNA(U106) and suppress second harmonic originated in the LNA(U106). The Rx RF SAW filter(U107) is
usually called image filter.

Rx IF SAWFilter (U108)
The Rx IF SAW filter(U108) protects its following stages from close-in Inter Modulation (IM) signals,
provides adjacent channel selectivity, and attenuates the second image.
RX_BBA (U109)
Rx_BBA is divided three main parts, IF frequency processing, base-band processing, and digital
interface. It is a receiver IC, installed with a Rx AGC, base-band converter, base-band analog filter, and
A-D converter. It can send a digital base-band signal to digital base-band IC.
The circuit functions of the RX_BBA(U109) include Rx Automatic Gain Controller (AGC) with 90dB
dynamic range input, quadrature IF mixers and Analog to Digital Converters (ADC) for converting to
digital base-band. The RX_BBA(U109) includes clock generators that drive the digital processor and the
VCO(U109) which generates the IF LO frequency for base-band down-conversion. The Rx AGC either
amplifies or attenuates the received CDMA IF signal to provide a constant-amplitude signal to the I/Q
down converter. The IF output of the Rx AGC amplifier separates into I-channel and Q-channel base-
band components and down- converted by mixer with quadrature LO. Rx IF LO signals are generated by
the Voltage Controlled Oscillator of Rx IF. Frequency is stabilized by external varactor-tuned resonant
tank circuit. The I/Q down converter outputs the CDMA signals at base-band frequency. Low-pass
filtering enables the receiver to select the desired base-band signals from the effects of unwanted noise
or adjacent-channel interference. I/Q base band components are converted to digital signals by two
identical 4-bit ADCs. The Block Diagram of the RX_BBA(U109) is shown in Figure 4.6.

4.2.3 Description of Tx Part Circuit
The 8 bit digital signal fed into TX_BBA(U112) passes through DAC using TXCLK and TXCLK/ as
triggers to produce base band I/Q signal. Inside the MSM(U125), each signal is sent out to the up mixer via
a digital low pass filter. At the mixer, 130.38 MHz I/Q signal obtained by dividing the 260.76MHz VCO
signal by half is used as carrier for the up-conversion of base band signal to Tx IF signal. This signal is
again up-converted into Tx RF frequency signal. The signal converted into Tx RF frequency is amplified at
the drive amplifier. At the Tx AGC AMP, this Tx IF signal level is varied according to the several
parameters defined in mobile station and base station. The proper gain control signal comes out from the
MSM(U125) in the waveform of PDM and rectified to constant DC voltage level by RC low pass filter. The
gain variable range of Tx AGC AMP is 90 dB. The signal is amplified at the power amplifier. Finally, it is
transmitted out to antenna via a duplexer(F100).
TX_BBA (U112)
The TX_BBA(U112) Base-band-to-RF Transmit Processor including Tx AGC Amplifier, quadrature
mixers, IF synthesized PLL, RF single sideband up converter, RF driver and Tx IF VCO. It converts a base-
band analog signal coming from a digital base-band processor (Modem chip) to an analog RF signal to be
able to Tx PAM.
The TX_BBA(U112) offers the most advanced and integrated CDMA Tx solution along with minimized
power consumption for extended talk-time performance.
The TX_BBA(U112) connects directly with QUALCOMM’s by the MSM(U125) utilizing an analog base-
band interface. The base-band quadrature signals are up-converted to the cellular band and amplified to
provide signal drive capability to the PAM(U110). The TX_BBA(U112) includes an IF frequency, single
sideband up-conversion from IF to RF, two cellular driver amplifiers, and Tx power control through an 85dB
VGA. TX_BBA(U112) functionality is specifically controlled from the MSM(U125) via the three-line serial
bus interface(SBI).
The Block Diagram of the TX_BBA(U112) is shown in Figure 4.7.
Power Amplifier Module (U110)
The power amplifier Module(PAM,U110) that can be used in the CDMA has linear amplification
capability, whereas in the FM mode, it has a 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 GaAs HBT (heterojunction bipolar transistor) process.
The PAM(U110) is made up of an output end interface circuit including this MMIC. The RF transmit
signals that have been amplified through the PAM(U110) are sent to the duplexer(F100).
