摘要
阐述了平行耦合微带线带通滤波器的基本原理。在介绍此种滤波器传统设计方法的基础上,结合实例介绍一种利用耦合微带线奇偶模阻抗计算程序并结合ADS(Advanced Design System)仿真设计软件设计此种滤波器的方法。
The realization of band-pass filters using parallel coupled microstrip lines is very popular in microwave systems. In this paper, the basic theory and traditional design method of parallel coupled microstrip filters is described firstly. And then a design method of this kind of filters using an odd-mode and even-mode impedance of coupled-lines calculating programme and ADS (advanced design system) simulation software is presented. An example is presented.
