| 摘 要： | 提出了一种全新的能够处理复杂非互易传输线(NTL)问题的标准Smith圆图解法。该解法基于一种非线性映射关系，将NTL模型的参数转化为传统互易传输线(RTL)模型的参数，从而可利用标准的Smith圆图(SSC)完成NTL中的设计和参数计算等问题。为了验证解法的有效性和简便性，以NTL单支节串联匹配和双支节并联匹配为例，给出了完整的设计与验证过程。

| Abstract: | A new approach for solving complicated nonreciprocal transmission line(NTL) problems using standard Smith chart is proposed.Based on a nonlinear mapping,it transforms the parameters of NTL model into the parameters of traditional reciprocal transmission line(RTL) model.As a result,the design and calculation in NTL can be easily done by using a standard Smith chart(SSC).The effectiveness and convenience of the approach is tested through the complete design process of NTL single-stub series-matching and NTL double-stub parallel matching network. |
