本文提出了一种新的模块化设计椭圆滤波器的积木。被称为双合模的构建块包含两个谐振器，它们在通带的两侧产生一个传输零点。高阶滤波器可以通过级联双合滤波器来设计，类似于级联三合滤波器和四合滤波器。双合线表现出一些有趣的零点漂移特征，这些特征在三合线和四合线中不存在。其中一些功能进行了讨论，在矩形波导中的所有电感偶滤波器。矩形波导技术的高阶滤波器也提出了沿着与其他技术，如带状线和微带实现的建议。
The paper presents a new building block for modular design of elliptic filters. The building block, called doublet, contains two resonators which generate one transmission zero on either side of the passband. Higher-order filters can be designed by cascading doublets similarly to cascade triplets and quads. The doublet exhibits some interesting zero-shifting features which are not present in triplets and quads. Some of these features are discussed in connection with all-inductive doublet filters in rectangular waveguides. Higher-order filters in rectangular waveguide technology are also presented along with suggestions for implementation in other technologies such as stripline and microstrip.
