微带低通滤波器迭代分析设计法

内容简介：对于衰减零极点在jw轴上适当分布的微带线低通滤波器，通过迭代分析进行设计，可以计及微带不连续性的影响，提高设计精度。基于迭代分析法，本文采用非等波纹逼近方式，选取高阻抗传输线节和分支短截线节的长度为设计变量，从而使设计比较简捷。这一工作对于促进MIC设计技术的发展，具有积极意义。

Abstract：For the microstrip low-pass filters with attenuation poles and zeros located at jωaxis, a design method of iterated analysis is presented in this paper. The design procedure takes into account the effects of all discontinuities in the microstrip, so that the design accuracy may be increased. By using non-equiripple approximation the lengths of transmission lines and branch stubs with high impedance are used as the design variables, the design procedure becomes simple and direct. The work is helpful for the development of MIC technique.
