Ampleon announces a wideband system solution that uses Xilinx’s Digital Pre-Distortion (DPD) IP with Xilinx All Programmable SoC and MPSoC technology.
DPD and power amplifier (PA) efficiency improvements are closely related, because PAs with higher efficiencies tend to be less linear and more difficult to pre-correct. Advanced pre-distortion systems are needed to recover the wanted linearity. The advent of wide-band and multiband systems poses additional challenges to the pre-distortion system, because of the increased signal bandwidth that needs to be processed. While Ampleon develops solutions for amplifiers able to cope with ever increasing signal bandwidth, Xilinx’s DPD solutions work to linearize them. A close cooperation is needed in order to optimize the full system, PA and linearization system, using dedicated algorithms and state of the art programmable hardware.
