PMC introduced their UniTRX chipset for macro basestation designs. The new integrated radio transceiver chipset replaces up to 14 discrete devices. In addition, the UniTRX chipset reduces both board space and power by over 50% for equivalent multi-standard basestation radio designs. The devices are rated for industrial temperature operation (-40° degrees to +85° degrees Celsius). Key components of the UniTRX chipset are sampling now.
The UniTRX radio transceiver chipset is designed to support wideband modules operating in the 400MHz to 4GHz 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 ideal 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.
The UniTRX chipset includes three integrated monolithic CMOS devices:
A dual-transmitter RFIC for multi-standard, wideband radio designs. It 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.
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.
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.
