摘　　要：通过对不同结构的广义切比雪夫型LC滤波器的传输零点特性进行分析验证,得到适用于N阶广义切比雪夫型LC滤波器传输零点特性的结论。基于这些结论提出一种快速设计广义切比雪夫型LC滤波器的方法,大大缩短了设计滤波器的时间。并且该方法可以在实现滤波器带外截止特性的同时,实现滤波器小型化,在科学研究和工程应用中具有重要意义。Based on the characteristic analysis of transmission zeros of generalized Chebyshev LC filters with different struc-tures,some conclusions suitable for transmission zeros′ characteristics of N-order generalized Chebyshev LC filter were obtained. Based on the conclusions,a rapid design method of generalized Chebyshev LC filter was proposed,which can greatly shorten the design period,and can realize the filter cut-off characteristics as well as the filter miniaturization at the same time. It has an important significance in scientific research and engineering applications.
