Overview

Preliminary Information SATURN 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 AGC amplifiers with 90dB of variable gain, fully compensated for temperature variation IQ demodulator with accurately defined output DC level and low DC offsets LO operating at twice frequency with high accuracy quadrature generation Sophisticated power management control operation Overload indicator Odering Information SATURN/KG/QP1S SATURN/KG/QP1T q q 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.
