Overview
INTEGRATED CIRCUITS SA1638 Low voltage IF I/Q transceiver Product specification IC17 Data Handbook 1997 Sept 03 Philips Semiconductors Philips Semiconductors Product specification Low voltage IF I/Q transceiver SA1638 DESCRIPTION The SA1638 is a combined Rx and Tx IF I/Q circuit.
The receive path contains an IF amplifier, a pair of quadrature down-mixers, and a pair of baseband filters and amplifiers.
A second pair of mixers in the transmit path transposes a quadrature baseband input up to the IF frequency.
An external VCO signal is divided down internally and buffered to provide quadrature local oscillator signals for the mixers.
A further divider chain, reference divider and phase d...
