Ampleon announced it will demonstrate a wideband system solution at IMS 2016 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.
“Advanced digital pre-distortion algorithms are needed to linearize PAs for wide-band and multi-band applications to achieve desired performance while lowering CAPEX and OPEX,” said Harpinder Matharu, Senior Product Manager, Communications Business at Xilinx. “Together at IMS 2016, we will be highlighting high power efficiency for wide signal bandwidth radio applications and demonstrating an advanced digital pre-distortion solution, available on Xilinx 28nm Zynq® SoC and UltraScale+™ MPSoCs. This will showcase linearizing Ampleon’s state of the art PAs consisting of an MMIC Driver BLM8G2327S-25PBG and a 2.5 to 2.7 GHz 300 W LDMOS asymmetric Doherty power transistor.”
A joint live demonstration of a wideband system (DPD and PA) is shown during IMS2016 on the Ampleon booth, #2149.
