CML launches CMX991 transceiver IC
A CML Microcircuits product story
Edited by the Electronicstalk editorial team May 4, 2009
CML Microcircuits has unveiled a high-performance integrated RF quadrature/low IF transceiver IC featuring an advanced image-reject up-conversion modulation system and a superheterodyne receiver.
The CMX991 is designed to meet the global requirements of electronics designers searching for a low-cost integrated transceiver device that offers consistently precise RF signal processing.
Specifically tailored for flexible operation from 1GHz down to 100MHz, the transceiver addresses an area that is not adequately covered by existing devices on the market, according to the company.
CML's RF transceiver IC suits both narrowband and wideband wireless products and features up to 2MHz RF channels, including multi-mode analogue/digital terminals and digital software-defined radio (SDR) for portable, mobile and base-station designs.
The CMX991 is targeted at a number of applications, including APCO Project 25 (Phase 1 and 2), ETSI DMR (TS 102 361), general-purpose wireless data applications and satellite-communication systems.
It integrates the core functions to implement a high-performance RF transceiver subsystem, with I/Q architecture capable of supporting multiple modulation types and bandwidths.
The company claims that the device features good intermodulation performance, an on-chip first mixer, direct access to transmit and receive IF sections and a selection of external components for multi-mode operation.
A low IF output mode is supported in the receiver for designers using 'Sample at IF' techniques.
The CMX991 provides maximum integration and minimum overall manufacturing BOM cost.
The device, which is available now with a quantity guide price of USD10 (GBP7), operates at 3.3V (1.8V I/O) and comes in a 48-pin VQFN package.
For designers wanting to experiment with the product, an evaluation kit (EV9910B) is available from CML, a provider of low-power semiconductors for global communications markets.
