摘要
本文采用不定散射矩阵导出了串联、并联、混联和Ｍａｓｏｎ反馈放大器的走散射矩阵显式表达式，提出了一种反馈放大器噪声参数的简化分析法，从而可快速分析微波反馈放大器的传输和噪声性能。在此方法的基础上，以知识库为支持，实现了微波固态反馈放大器的自动设计。
The explicit formulas of S matrix for the typical feedback amplifiers are derived by the use of indefinite S matrix, and a simplified noise figure calculating method is suggested. These can be used to determine the transmission and noise performance of feedback amplifiers conveniently. Based on these methods, a knowledge-based automatic design procedure for microwave solid-state feedback amplifiers is developed.
