微带三等分交叉耦合滤波器的分析与设计

Design of Cascaded Trisection Microstrip Filters

三等分交叉耦合是一种新型的耦合结构;用其所设计的滤波器具有一些独到优势。本文对L波段微带三等分交叉耦合滤波器进行了理论探讨,给出了其基本物理结构和设计实例。通过利用Ansoft designer软件对设计的滤波器进行仿真,表明了其在高选择性滤波和一些特殊要求滤波应用方面的独到优势。

It＇s a new coupling structure of trisection cross-coupling; filters designed in this way will have some original superiority. This article discussed the cascaded trisection microstrip filters in theory, provided the basic physical strueture and design examples. From the simulation result, we can see that it has the original superiority to be used for high selective filters and special filters.
