摘要:
建立同轴腔加载波导滤波器系统的等效电路模型,在波导短路端面与同轴探针弱耦合状态下,通过求解回路方程组得到3个谐振频率点,分别对应π/2模、0模和π模,频率间隔决定于耦合系数.强耦合状态下,该模型仅存在1个谐振频率点,波导只起传输信号及滤波作用.通过实验测量波导滤波器系统正向传输系数曲线,在弱耦合状态下获得3个谐振频率点,强耦合状态下仅存在1个谐振频率点,结果与理论分析一致.
Abstract:
We establish an equivalent circuit model to analyze the coaxial cavity coupled with waveguide filter. By solving the circuit equations, we derive three resonant frequencies of π/2 mode, zero mode and π mode in the case of weak coupling. The resonant frequency internals for three modes depend on the coupling coefficient. There is only one resonant frequency in the case of strong coupling. We test the forward transmission coefficient of waveguide filter system. We obtain three resonant frequencies for weak coupling case and one resonant frequency for strong coupling case in experimental measurements. The results agree well with theoretical predictions.
