| 摘 要： | 通过对广义Chebyshev滤波器设计的深入研究，提出了由指标得到传输零点的综合方法，再利用三腔结构确定网络拓扑结构并采取优化算法求解交叉耦合矩阵，最后用Ansoft HFSS建立同轴腔体滤波器模型，仿真结果与理论结果吻合得较好，验证了这种综合方法的有效性．

| Abstract: | Through the research on the design of the general Chebyshev filters, a comprehensive method of calculating transmission zeros is brought forward according to the given targets. Furthermore, the topological structure of the filter is determined form CT, and the coupling matrix is generated by using the optimization algorithm. Finally, the model of coaxial cavity filter is established with Ansoft HFSS. The simulation result agrees very well with theoretical one, so the effectiveness of the synthesis method is verified. |
