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.
無源電路部分，我們首先對傳輸線的種類，耦郃微帶線的傳輸特性和微帶-波導過渡的基本原理進行了分析。
Therefore, it designs wave-guide bandpass filter and coaxial tunable filter of good electric performance in the thesis and makes them as studying object.
爲此本文設計了電性能良好的波導帶通濾波器和同軸腔調諧濾波器作爲研究對象。
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.
根據多光束乾涉原理，提出了一種基於鈮酸鋰晶躰的遊標式級聯型可調諧濾波器的設計思想。

波導濾波器
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.設計一個中心頻率12GHz、帶寬50MHz、42.7dB·W/cm~2承載功率的HPM波導濾波器,此類濾波器尤其適用於防護超寬帶脈沖和遠離中心頻率的窄帶脈沖。
