提出了一种新的带通滤波器直接耦合矩阵合成方法。与现有的合成方法不同，提取的极段和剩余的交叉耦合谐振腔是统一合成的。因此，合成的耦合矩阵既包含谐振节点，也包含非谐振节点。该方法合成的耦合矩阵的另一个显著特征是其频率响应可能涉及一定的相位偏移，这可以从我们的合成方法中确定。
A new direct coupling matrix synthesis approach for bandpass filters with extracted-poles is presented. Different from existing synthesis methods, the extracted-pole sections and the remaining cross-coupled resonators are synthesized in a unified approach. As a result, the coupling matrix synthesized contains both resonant and non-resonant nodes. Another distinct feature of the coupling matrix synthesized by the proposed approach is that its frequency response can involve certain phase offset, which can be determined from our synthesis approach.
