And then , we analyze the nonlinear properties of limiting amplifier . due to the typical nonlinear properties of limiting amplifier , we studied the method of academic analysis for microwave nonlinear circuit and the nonlinear circuit model of transistor in detail 由于微波限幅放大器的工作是典型的非線性特性,我們研究了非線性電路的分析方法和微波晶體管的非線性模型,詳細(xì)得介紹了諧波平衡法這種重要的非線性電路分析方法。
