摘要
针对单端口微波网络的群时延特性、并联谐振与串联谐振两种谐振器,在单端口网络中的群时延特性做了推导。得到群时延特性中S参数与谐振腔品质因数之间的关系,分析了两种负载情况下群时延特性的变化情况,得出单端口网络不随负载变化而变化的结果,有助于研究谐振器的外部耦合特性。
Group delay with microwave single-port group network is deduced in this paper.The relevance between the S-parameter and Q-factor of resonator is obtained by deducing the group delay characteristic of shunt-resonant circuit and series-resonance circuit.The variation of group delay characteristics with two different loads are analyzed,indicating the fact that single-port network does not vary with the change in loads,a valuable conclusion for the study of external coupling characteristics of the resonator.
