摘要
微波组件设计中,宽带微波组件工作时出现谐振自激的现象不时发生。当组件出现谐振自激时,一般采用粘贴吸波材料的方法进行消除。波导理论虽然非常成熟,但直接用于解决工程问题比较少。提出通过仿真计算腔体的主模以及高次模频率的方法,在详细设计之前就规避了谐振频率处于组件工作频段内,解决了频综组件工作频段内某频点失锁的问题。
The phenomenon of resonant self-excitation occurs from time to time during the operation of wideband microwave assembly.When resonance occurs in the assembly, it is generally eliminated by pasting absorbing materials.Although waveguide theory is very mature, it is not easy to be used directly to solve engineering problem.A method is proposed to avoid the resonant frequency in the working band of the component at the beginning of design: the main mode and higher-order mode frequencies of the cavity are calculated by simulation.The problem is solved that a frequency point in the working frequency band of the frequency synthesizer loses its lock.
