SATURN
CDMA/AMPS dual Band IF Receiver for Digital Phones
Preliminary Information
DS4721
Issue 4.2
April 1999
Features
q Selectable IF input buffers with characteristic
impedance suitable for interface to IF CDMA and
FM SAW filter outputs
Odering Information
SATURN/KG/QP1S
SATURN/KG/QP1T
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
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.
