Abstract :
This paper presents a novel technique for software based compensation for three most important aspects of SSPA i.e. gain compensation, back-off attenuation and drain compensation over large temperature range. It was conceptualized and implemented using Lange based reflective attenuation microwave circuit with PIN diodes and FPGA. An algorithm has been developed and implemented in FPGA hardware using LUTs created by measured SSPA performance A novel approach is used to store these numbers.
