| 摘 要： | 该文首先提出了含源-负载交叉耦合滤波器的等效网络模型,并给出了这种结构的传输函数t(s)以及矩阵的综合方法。由含源-负载交叉耦合二端口网络的短路导纳矩阵推导了耦合矩阵M中MSL、MSi和MiL的一般表达式。最后,设计了一种新颖结构的含源-负载交叉耦合的微带滤波器,对其进行了仿真与制作,实测结果与仿真值、理论值吻合较好。

| Abstract: | A general method is presented for synthesis of quasi-elliptic filter with source-load coupling. The equivalent circuit of the low-pass prototype of a lossless coupled resonator filter is proposed, as well as its transfer function t (s ).The expressions of MSL, MSi and MiL in the coupling matrix M are obtained based on two-port admittance matrix [ YN ]. Finally, a novel quasi-elliptic two pole microstrip filter composed of two hexagonal open-loop resonators is designed. The numerical results are verified with the simulation, The measured and simulated data are in good agreement. |
