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。
針對單耑口微波網絡的群時延特性、併聯諧振與串聯諧振兩種諧振器,在單耑口網絡中的群時延特性做瞭推導。得到群時延特性中S參數與諧振腔品質因數之間的關繫,分析瞭兩種負載情況下群時延特性的變化情況,得齣單耑口網絡不隨負載變化而變化的結果,有助于研究諧振器的外部耦閤特性。

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.
