摘要

本文提出了一种基于软件的SSPA增益补偿、回退衰减和大温度范围漏极补偿三个重要方面的补偿方法。采用基于Lange的反射衰减微波电路,结合PIN二极管和FPGA实现了该系统。利用测量SSPA性能产生的lut,在FPGA硬件上开发并实现了一种算法,并采用了一种新的方法来存储这些数字。

An algorithm implementation for gain control and power compensation in power amplifiers
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.
