- 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，对于两个不对称度很高的双通带同样有效，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。
- Abstract:
- This passage provides a new method for microwave filter’s polynomial synthesis. The method combines frequency transformation and optimization. Compared with the method of frequency transformation which is good at the synthesis of symmetric dual-passband filters, the new method this passage gives will work out well for both symmetric and asymmetric dual-passband filters. After synthesis with this new method, the frequency response in the passbands is equi-ripple and the two passbands have the same maximum return loss. Several design examples are listed out for the validation of the new method.
