摘要

提出了一种利用短端假腔进行双模腔滤波器调谐的方法。调谐是基于计算和测量的反射系数相位响应的匹配。采用等效电路模型计算反射系数所需的相位响应。将该方法应用于四极直列式双模椭圆响应滤波器，验证了该方法的有效性。实验结果表明，该方法与计算结果吻合较好，不需要进行额外的整定。

A tuning method using a dummy cavity for dual-mode cavity filters

A tuning method using short-ended dummy cavity is presented for dual-mode cavity filters. Tuning is based on the match of the computed and measured phase response of reflection coefficient. Equivalent circuit model is adopted for computing required phase response of reflection coefficient. This proposed method is applied to 4-pole in-line type dual-mode elliptic response filter for demonstration of this new method. It is shown that this method shows good agreement between the experimental and computed result, and no additional tuning procedure is required.
