Research on network synthesis method of microwave multiplexer

在滤波器多项式综合基础上,将多项式综合技术在多工器上做了推广,将传统的多项式综合技术从传统的双端口网络拓展到多端口网络,并且给出综合实例。该方法是在归一化频率中综合考虑各路滤波器之间的相互影响,运用迭代算法综合得到多工器的的特征多项式。最终综合结果满足设计指标,同时也验证了这种方法的可行性。

Based on the filter polynomial foundation,the polynomial synthesis technology is applied to the multiplexer. The polynomial synthesis technology was expanded from the traditional twoport network to multiport network. The examples are given in this paper. In this method,the interaction among filters is considered in the normalized frequency. The characteristic polynomial of the multiplexer was obtained by means of the iterative algorithm. The final comprehensive results satisfies the design index. The feasibility of the method was demonstrated.
