waveguide filter

基本解释

In passive section, Above all, I introduce theory about microstrip line. Millimeter-wave band-pass filter and wave guide-to-microstrip transition.
无源电路部分，我们首先对传输线的种类，耦合微带线的传输特性和微带-波导过渡的基本原理进行了分析。
Therefore, it designs wave-guide bandpass filter and coaxial tunable filter of good electric performance in the thesis and makes them as studying object.
为此本文设计了电性能良好的波导带通滤波器和同轴腔调谐滤波器作为研究对象。
With the principle of multiple-bean interference, an integrated electro-optical tunable wave-guide filter is designed by using cascaded Fabry-Perot cavity based on LiNbO_3.
根据多光束干涉原理，提出了一种基于铌酸锂晶体的游标式级联型可调谐滤波器的设计思想。

波导滤波器
A HPM wave-guide filter is designed,which with the parameters of central frequency 12GHz, bandwidth 50MHz,carrying power 42.7dB·W/cm~2. This kind of filter,being used to defend UWB and narrow bandwidth pulse deviation from central frequency,is particularly effective.
3.设计一个中心频率12GHz、带宽50MHz、42.7dB·W/cm~2承载功率的HPM波导滤波器,此类滤波器尤其适用于防护超宽带脉冲和远离中心频率的窄带脉冲。
