摘　　要：介绍一种微波低频段腔体滤波器的设计方法。首先给出多种加载腔体的结构形式进行分析比较,并通过2个设计实例和测试结果,证明采用双同轴腔体加载形式,可以实现结构的微型化。该结构与普通的加载型腔体滤波器相比,谐振器长度可以极大缩短,腔体也能保持比较高的Q值。A design scheme of lower band microwave cavity filter is introduced in this paper. It analyzes and compares several structures of load cavity. By comparing two design examples and test results,it is shown that it is possible to realize micromation structure by load form of double coaxial cavity. Comparing with general load cavity filter, the length of this resonator is maximum shorted, and the cavity can be kept higher Q.
