Radio transceiver chipset for macro base stations
19 September 2012, Telecoms, Datacoms, Wireless, IoT

PMC announced a low-power, highly integrated radio transceiver chipset for macro base station designs. The new UniTRX chipset replaces up to 14 discrete devices, and reduces both board space and power for equivalent multi-standard base station radio designs. It addresses multi-standard macro base station performance requirements and simplifies the design of dense MIMO (multiple input, multiple output) radio units, such as active antenna systems.

The chipset includes three integrated monolithic CMOS devices:

UniTX is 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.

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 synthesiser 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 base station 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.
