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

● 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
