摘要:

介绍了一种通过特征多项式综合多工器耦合系数的方法。该方法在低通原型频域中运用迭代算法计算优化多工器整体及各支路滤波器的特征多项式,综合得出的各支路耦合系数考虑进了多工器其余支路的影响,大幅缩短滤波器优化时间,且各支路滤波器的传输零点位置可根据需要指定。该方法也适用于双工器及三工器的推导。最终利用软件Ansoft Designer,综合设计并检验一个四工器,利用该方法得出的曲线与预期吻合。

关键词: 多工器, 滤波器, 特征多项式, 综合

Abstract:

This paper illustrates a method for the synthesis of microwave multiplexer with characteristic polynomial.Using iterative algorithm,the characteristic polynomial of multiplexer and arm filter can be optimized in a law-pass frequency domain.By this method,the coupling coefficient can be calculated for each branch.With the impact of the remaining branches of the multiplexer in consideration,the filter optimization time is shorter than before.The transmission zeros of each branch filter can be given any value.The method is also applicable to the synthesis of duplexer and multiplexer.Finally,using software Ansoft Designer,a multiplexer is designed.The simulation curve is consistent with the expected one.

Key words: multiplexer;filter;characteristic polynomial;synthesis
