摘要
文章提出了一种新的微波双通带滤波器多项式综合技术,这种方法将频率转换与优化方法结合,与频率转换方法相比较,文章中提出的新方法不仅能够有效地综合出具有等波纹响应特性的对称双通带滤波器的S参数多项式,而且对于两个不对称度很高的双通带也同样有效。文章最后给出了相应的设计实例,验证了该方法对所有双通带多项式综合的有效性。
Polynomial synthesis method for microwave dualband filter combined with frequency transformation and optimization is proposed in the paper. Compared with frequency transformation method, the proposed method is good at synthesizing S-Parameters polynomial for both symmetric and asymmetric dualband filters. Some examples are designed to verify the effectiveness for dualband filter in the end.
