RF transceiver targets radio designers with high performance and flexibility
CML Microcircuits 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 CML’s new RF transceiver IC suites both narrowband and wideband wireless products – up to 2MHz 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.
