一种新型交叉耦合同轴腔体滤波器的设计与实现

Design and Realization of a Novel Cross——Coupling Coaxial Cavity Filter

交叉耦合同轴腔体滤波器具有谐振单元少、体积小、带外抑制高等优点，在现代通信领域得到了广泛的应用，此前已有一些文献对此类滤波器进行过研究，本文在此基础上提出了一种新型的在工程上易于实现的八腔交叉耦合同轴腔体滤波器结构，并利用自己编制的仿真软件，对该滤波器进行仿真和优化设计。实际制作结果表明，滤波器完全达到了指标要求，理论仿真结果与测试结果吻合良好。

Cross- coupling coaxial cavity filter has been widely used in the field of modern communication due to the virtues such as few resonators, small mass and perfect stopband rejection. They have been investigated by many researchers.Based on these researches ,a novel eight-pole cross-coupling coaxial cavity filter is designed, abricated, and tested in this paper .The parameters of this filter are simulated and optimized by commercial microwave simulation software designed by myself. The results of theory and experiment have good coherence by comparing.
