Nujira and Xilinx complete FPGA envelope tracking reference design
Cambridge, UK, 23 February 2011 – Nujira and Xilinx today announced the first successful integration of envelope tracking (ET) technology with a third-party digital pre-distortion (DPD) solution running on an FPGA. The two companies have delivered a reference design for a cellular base station PA circuit with Nujira’s Coolteq.h envelope tracking modulator linearised by a Xilinx DPD block running on a Xilinx Virtex 6 FPGA platform. Envelope signal generation in the FPGA was implemented using Nujira’s Envelope Generation Interface, which is compliant with the openET Alliance’s specification for infrastructure ET modulators.
