摘要
移动通信网络建设过程中,腔体滤波器的应用十分广泛,然而目前的腔体滤波器的仿真设计与实物加工往往存在较大偏差。该背景下,介绍了一种腔体滤波器仿真方法,采用导纳矩阵提取滤波器的耦合矩阵及谐振频率,通过优化和迭代从而达到腔体滤波器全腔精确仿真的目的。通过实例分析与样品制作,验证该方法可行,仿真效率与精度均大幅提升。
During the construction of mobile communication networks,cavity filters are widely used,but there are often significant deviations between the simulation design and physical processing of current cavity filters.In this context,the article introduces a simulation method for cavity filters,which uses admittance matrix to extract the coupling matrix and resonant frequency of the filter.Through optimization and iteration,the goal of accurate simulation of the entire cavity of the cavity filter is achieved.Through case analysis and sample production,it is verified that this method is feasible,and the simulation efficiency and accuracy are significantly improved.
