寄生旁路耦合，特别是发生在紧凑的高阶模式腔体滤波器，导致所需的理想响应的明显恶化。通过对TE/sub 301/模腔体滤波器设计的研究，解释了产生这种不必要耦合的原因。基于这一知识，建立并实验验证校正措施，以补偿与理想滤波器响应的不必要偏差。此外，这种旁路耦合可用于改善先进腔体滤波器设计中的响应。>
Parasitic bypass couplings-occurring especially in compact higher order mode cavity filters-cause evident deterioration of the desired ideal responses. The study of a TE/sub 301/ mode cavity filter design gives an explanation of the reasons of such unwanted couplings. Based on this knowledge, corrective measures are established and experimentally verified to compensate for unwanted deviations from the ideal filter response. Moreover, this kind of bypass coupling can be utilized to improve the response in advanced cavity filter designs. >
