摘要: 本文提出一种用于微波非线笥电路分析的时域－谱平衡算法，这种算法可以用于各种数字调制信号激励的微波非线性电路的分析，尤其适用于频分多址的数字调制信号的分析。利用算法，分析了ＱＰＳＫ信号激励的微波放大器，所得模拟结果与理论分析吻合。Abstract: A new method,which can be used to analyze the microwave nonlinear circuits,is presented in this paper.This method can be used to analyze the microwave circuit excited by any kind of digitally modulated signal,especially the signal of FDMA.Using this method,a power amplifier excited by the QPSK signal is analyzed.Agreement with the theoretical deduction is achieved.
