摘要
文章介绍了一种利用微波带通滤波器的时域反射损耗(即S11)曲线分析和调试滤波器的方法,运用此法在调试滤波器时可以快速地分析出具体是哪一个谐振电路或耦合器需要调试,以便对其进行专门的修正和调试,从而节省调试时间,简化调试过程。同时也介绍了3种方法作为把频域数据转换为时域数据的理论基础,即傅里叶级数法、快速傅里叶变换法和Chirp-z变换法,并对这3种方法作了相应的评价。
A new method of analyzing and tuning band pass filters based on the time domain response of the return loss（S11 ） is studied in this paper. With this method, the resonator and coupler needed to tuned can be and can be precisely set to a desired filter response, so that a filter can be designed or tuned in less time, more easily and accurately.
