General Description

The CMX991 is a single-chip, high performance, RF transceiver that provides the core functions required to implement a full-featured radio transmitter and receiver.

It operates from 100MHz to 1GHz and its I/Q architecture supports multiple modulation types and bandwidths with a single radio design.

The half-duplex CMX991 integrates Tx modulators, Rx demodulators, IF PLL and IF VCO subsystems to minimise the external circuits needed when implementing a plete transceiver.
