广义切比雪夫滤波器综合的统一理论
程晓辉,李 杰
(西安电子科技大学 机电工程学院,陕西 西安 710071) 摘 要 无线通信系统需要高性能的交叉耦合滤波器。交叉耦合滤波器的综合从给定的传输零点和回波损耗 出发,直到得到各腔体之间的耦合系数。该文介绍在同一电路拓扑结构下提取耦合矩阵的统一理论,可同时实现 带通和带阻滤波器的综合方法。 关键词 微波滤波器;带通/带阻滤波器;耦合矩阵 中图分类号 TN713
The Uniform Theory of Synthesis of Generalized Chebyshev Filter
Cheng Xiaohui, Li Jie
(School of Electro-Mechanical Engineering, Xidian University, Xian 710071, China) Abstract The cross coupled microwave filter is widely used in the mobile communication subsystem. The synthesis of the cross coupled filter is from prescribed transmission zeros and return loss till the attainment of the coupling matrix of each cavity. In this paper the uniform theory of extracting coupling matrix with the same circuit topological structure is introduced and the same coupling sc……
