摘要
该文对前馈线性校正射频功率放大器进行了分析,给出了分析结果。并用该结果指导设计了CDMAIS-95基站射频线性功率放大器,放大器增益47dB,连续波输出功率60W,在通频带内三阶交调改善了23dB。
In this paper, a novel analysis of feedforward linearizing power amplifier is presented. Experimental results are reported for a CDMA IS-95 base station feedforward linearizing amplifier, which demonstrates a minimum of 23dB intermodulation distortion suppression when the amplifier's gain is 47 dB and continue wave output power is 60W.
