非互易传输线问题的标准Smith圆图解法

A Novel Approach for Solving Nonreciprocal Transmission Line Problems Using Standard Smith Chart

提出了一种全新的能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.

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.
