DESCRIPTION
The SA1630 is a 70–400 MHz I/Q transceiver for wireless LAN.
The Receive Path contains a digitally gain controlled linear IF amplifier, a pair of quadrature down conversion mixers and a pair of baseband
amplifiers.
The transmit path contains a pair of quadrature up conversion mixers that transposes a quadrature baseband input signal up to IF frequency.
An external VCO signal is divided internally and provides quadrature local oscillator signals for the mixers.
