微波谐振模型及其3dB-Q值

Micorwave Resonance Model and Its 3dB-Q

本文通过网络方法对通过式谐振腔的性质进行了深入分析 ,指出它不同于传统的并联谐振模型 ,进一步推得通过式谐振腔的 3dB Q值公式 ,其结果与微扰法、复频率法的结果近似相等 ,它为微波工程中半功率点法Q值的理论提出了重要佐证 .

The characteristic of the pass through resonance cavity is studied in this paper, which distinguishes itself from the traditional parallel connection resonance model. This paper also gives the Q equations of pass through resonance cavity, which is similar to the result obtained by perturbation method or complex frequency method. This process is the theoretical basis of measuring Q by half power points method in microwave engineering.
