Ampleon announced that they will demonstrate a wideband system solution at IMS 2016 that uses Xilinx’s Digital Pre-Distortion (DPD) IP with the Xilinx All Programmable SoC and MPSoC technology.
DPD (Digital Pre-Distortion) 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. This advent of a 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 the 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 capital expense and operating expense. Together, they 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) will be shown at IMS 2016 in San Francisco today at Ampleon booth, #2149.
