RF Transceiver Targets Radio Designers with High Performance and Flexibility
 May
1, 2009 -- CML Microcircuits, a leading innovator and provider
of low-power semiconductors for global communications markets, has introduced
a high performance integrated RF quadrature/low IF transceiver IC, which
features an advanced image-reject up-conversion modulation system and
flexible superheterodyne receiver.
The new
CMX991 is designed to meet the global requirements of electronics
designers, who are searching for a low cost integrated transceiver device,
which offers consistently precise RF signal processing. Specifically
tailored for flexible operation from 1GHz right down to 100MHz, the
transceiver addresses an area that is not adequately covered by existing
devices on the market.
CML's new RF transceiver IC suits both
narrowband and wideband wireless products - up to 2 MHz RF channels,
including multi-mode analogue/digital terminals, digital software defined
radio (SDR) for portable, mobile and base station designs.
Intended
applications include APCO Project 25 (Phase 1 and 2), ETSI DMR (TS 102
361), general-purpose wireless data applications and satellite communication
systems.
The
CMX991 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 excellent
intermodulation performance, on-chip 1st mixer, direct access to transmit
and receive IF sections and a flexible 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
CMX991 is available now with a quantity guide price of $10.00, operates
at 3.3V (1.8V I/O) and comes in a 48-pin VQFN package.
For designers
wishing to experiment with the product, an evaluation kit (EV9910B)
is readily available from CML.
