CMX992 - RF Quadrature Transmitter and RF Quadrature/Low IF Receiver

Download the CMX992 datasheet PDF. This datasheet also covers the CMX991 variant, as both devices belong to the same rf quadrature transmitter and rf quadrature/low if receiver family and are provided as variant models within a single manufacturer datasheet.

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.

Key Features

  • Rx (CMX991 and CMX992) o RF mixer with output select o 1st IF input select o Selectable low IF outputs (450kHz/455kHz) o 1st IF Variable Gain Amplifier (VGA) o 1st IF Signal Level Indicator (SLI) o Two-mode demodulator o I/Q Zero-IF with differential outputs.
  • Tx (CMX991 only) o I/Q modulator to IF o Image-reject up-converter o IF and RF outputs.
  • IF (CMX991 and CMX992) o IF LO synthesiser o IF VCO negative resistance amplifier.
  • 3.3V low power operation.
