| 摘 要： | 两谐振腔间的耦合系数是带通滤波器设计中的一个重要参数，它直接影响着滤波器的带宽。根据Tamio Kawaguchi对耦合系数的定义，谐振腔间的耦合系数有正值、负值和零。基于此，文章讨论了一种梳状滤波器耦合系数随耦合窗及输入输出抽头位置的变化情况。

| Abstract: | The coupling coefficient between two resonators is a very important parameter to bandpass filter design. This parameter directly affects the bandwidth of a bandpass filter. According to Tamio Kawaguchi＇s definition of the coupling coefficient it may be positive, negative or may be zero. A method is presented in this paper for determining the combine filter＇s coupling coefficients that varies with the various size of the coupling area and the position of the input or output probes. |
