Lowest power radio transceiver chipset focuses on next-generation macro basestations

June 06, 2012 // By Paul Buckley
PMC is claiming industry's lowest power radio transceiver chipset for macro basestation designs. PMC's UniTRX chipset replaces up to 14 discrete devices, and reduces both board space and power by more than 50 percent for equivalent multi-standard basestation radio designs.

The chipset addresses multi-standard macro basestation performance requirements and simplifies the design of dense MIMO (multiple input, multiple output) radio units, such as active antenna systems.     

The UniTRX chipset includes three integrated monolithic CMOS devices.     

UniTX is a dual-transmitter RFIC for multi-standard, wideband radio designs. The chipset supports the JESD204B interface, includes high-performance data converters and small-signal RF functions, such as analog quadrature modulators and local oscillators. The device also integrates feedback sampling channels to support digital pre-distortion (DPD) and an embedded processor for control and calibration.     

UniRX is a dual-receiver RFIC for multi-standard, wideband radio designs. It supports the JESD204B interface, includes high-precision analog-to-digital converters, and small-signal RF functions, such as mixers and local oscillators.  An embedded processor is included for control and calibration.      

SyntheCLK is a low-phase-noise clock synthesizer with an integrated jitter attenuator. It integrates high-performance PLLs and VCO to condition and regenerate precision system clocks, and configurable low-noise outputs to distribute the clocks throughout the radio module.     

The UniTRX chipset is designed to support wideband modules operating in the 400 MHz to 4 GHz frequency range. It addresses the performance requirements of macro basestation transceivers that feature multiple standards, including MC-GSM, cdma2000, WCDMA and LTE. High integration and low power make the chipset suitable for single-sector radio module designs and scalable for MIMO applications, such as active antenna systems. In addition to IF radio architectures, the UniTX also supports Zero-IF designs.     


Key components of the UniTRX chipset are sampling now to lead customers. The devices are rated for industrial temperature operation (-40 to +85 degrees C).
