三间隙耦合输出回路间隙阻抗频率特性的测量

Simulation and Measurement of Gap Impedance of Three-Gap Coupled Output Circuit

从多端口微波网络等效的角度,讨论多间隙耦合输出回路间隙阻抗频率特性的测试问题,并以X波段三间隙耦合输出回路为例,分别从模拟测量和实际测量两个方面确定了其间隙耦合阻抗的频率特性,简化了测量过程,为三间隙耦合输出电路工程应用提供了有效的实验手段。

The gap impedance-frequency characteristics of the multi-gap coupled output circuit was modeled,simulated,and measured in the technique,developed on the basis of the equivalent microwave network theory.And the equations were derived to calculate the gap-impedance.In the paper,the gap impedance of the three-gap coupled output circuit in the X-band was evaluated by combining the simulated and measured results.After simplifying the gap-impedance equations,the odd points of the real part of the gap impedance in the designed bandwidth can be eliminated.Besides,the measurement of the gap impedance-frequency characteristics of the multi-gap coupled output circuit can be significantly simplified.
