基于单端输入阻抗零极点的耦合系数提取方法
Extraction Method for Coupling Coefficients Based on the Zero-pole Frequencies of the Single-ended Input Impedance
摘要
Abstract
The optimization extraction method for coupling coefficients is time-consuming. From the view of the zero-pole frequencies of the singled-ended input impedance, iterative calculation formulas to the coupling coefficients and resonator frequencies were deduced in detail. The algorithm is effectively applied to the extraction analysis of a practical 4-order Chebyshev resonator filter. Results are in good agreement with theoretical results, which proved the correctness and validity of the method.关键词
