Extraction of Finite Transmission Zeros and Cross-Coupled Structure Analysis of General Chebyshev Filters
摘要
Abstract
Compared with the traditional filter ,the introduction of finite transmission zeros of the cross‐coupled general Chebyshev filter has better characteristics out of band‐pass .The determination and extraction of transmission zeros is the precondition for the synthesis of the filter .According to the transmission zero point ,the reflection and transmission polyno‐mials can be integrated and the cross‐coupled matrix can be obtained .The coupled matrix contains some real features of filter elements ,The coupled matrix is changed and the coupling difficult to achieve is removed easily .The topological structure is obtained without the influence of the filter performance .A novel optimization method is used to determine the transmission zeros ,and the validity of the method is verified .关键词
