1.2.6 RFR6500 - Down-converter Mixers part (U105)

The RFR6500 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 Base-

band signals. The three down-converting Mixers (Cellular, PCS and GPS), and a programmable PLL for generating

RX LO frequency and an RX LO Buffer Amplifier and RX Voltage Controlled Oscillator. 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-98D and J-STD-018 specifications for Sensitivity, Two-Tone Inter-

modulation, and Single-tone Desensitization.

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

MSM6550A.

The specification of VX9700 Mixers is described below:

1.3 Description of Transmit Part Circuit

1.3.1 RFT6150 (U102)

The RFT6150 Base-band to RF Transmit Processor performs all TX signal-processing functions required between

digital Base-band and the Power Amplifier Modulator (PAM). The Base-band quadrate signals are up-converted to

the Cellular or PCS frequency bands and amplified to provide signal drive capability to the PAM. The RFT6150

includes mixers for up-converting analog Base-band to RF, a programmable PLL for generating TX LO frequency a

TX LO Buffer Amplifier and TX Voltage Controlled Oscillator, cellular and PCS driver amplifiers and TX power

control through an 85 dB VGA. As added benefit, the single sideband up-conversion eliminates the need for a band

pass filter normally required between the up-converter and driver amplifier.

I, I/, Q and Q/ signals proceed from the MSM6550A to RFT6150 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 RFT6150 converts baseband signals into RF signals. After passing through the upconverters,

RF signal is inputted into the Power AMP.
