摘要
传统波导滤波器能够识别微波以下以及低频波段,在微波以及毫米波段上,无法实现高频波的过滤以及波频导向,为此提出微波毫米波波导滤波器的改进设计方案。重新设计金属镀膜结构,改变识别波的频段,增加高频波识别能力;改进过滤等效电路,增设高频波导向功能,通过电起管的优化设计实现微波毫米波处理机制;改变电阻抗,增设高频波导同轴转换机制,通过一体化波导设计实现波导滤波作用,完成滤波器的改进。试验结果表明,改进后的滤波器能够在微波毫米波等高频波段完成对波频的过滤导向。
Traditional waveguide filter is able to identify under microwave and low frequency band,in microwave and millimeter wave band,unable to realize the high frequency wave filtering and frequency wave guide,therefore put forward the improved design scheme of microwave millimeter wave waveguide filter.Redesigning the metal coating structure,changing the frequency of the recognition wave,and increasing the identification ability of high-frequency wave;To improve the filter equivalent circuit,add the high frequency waveguide to function,and realize the microwave millimeter wave processing mechanism through the optimization design of the tube.By changing the electrical impedance,the coaxial transformation mechanism of high frequency waveguide is introduced,and the waveguide filtering function is realized through the integrated waveguide design,and the improvement of the filter is completed.The experimental results show that the improved filter can be used to filter the wave frequency in high-frequency wave band,such as microwave millimeter wave.
