Preliminary Information

SATURN

CDMA/AMPS dual Band IF Receiver for Digital Phones

Preliminary Information

Description

The SATURN circuit is designed for use in dual band dual

mode mobile phones (CDMA/AMPS). The circuit is

designed to be compataible with digital baseband and

mixed signal circuit chips from Mitel (Planet Chip-set)

and Qualcomm (MSM2 and BBA). A wideband AGC

amplifier allows the input of CDMA or AMPS signal paths

with a range power management control options.

Features

q

Selectable IF input buffers with characteristic

impedance suitable for interface to IF CDMA and

FM SAW filter outputs

q

AGC amplifiers with 90dB of variable gain, fully

compensated for temperature variation

q

IQ demodulator with accurately defined output DC

level and low DC offsets

q

LO operating at twice frequency with high accuracy

quadrature generation

q

Sophisticated power management control operation

q

Overload indicator
