CML Microcircuits has introduced a high-performance, integrated RF quadrature/low IF transceiver IC, which features an image-reject, up-conversion modulation system and flexible superheterodyne receiver.
The CMX991 is designed to meet the global requirements of electronics designers who are searching for a low-cost integrated transceiver device that offers consistently precise RF signal processing.
Specifically tailored for flexible operation in 1 GHz to 100 MHz, the transceiver suits both narrowband and wideband wireless products - up to 2 MHz RF channels, including multimode analog/digital terminals, digital software defined radio for portable, mobile and base station designs.
Intended applications include APCO 25 (Phase 1 and 2), ETSI DMR (TS 102 361), general-purpose wireless data applications and satellite communication systems.
The IC integrates the core functions to implement a high-performance RF transceiver subsystem, with I/Q architecture capable of supporting multiple modulation types and bandwidth.
Features include good intermodulation performance, on-chip 1st mixer, direct access to transmit and receive IF sections and a flexible selection of external components for multimode operation.
A low IF output mode is supported in the receiver for designers using 'sample at IF' techniques.
