微波矩形陶瓷密封窗

MICROWAVE RECTANGULAR CERAMIC WINDOW/

文章介绍一种大宽窄比的矩形陶瓷密封窗的设计和制作。λ＇＿ｇ为充满介质的波导中的波导波长，工作频率为２４５０ＭＨｚ，模型窗的驻波比小于１．１，漏气率小于１．３×１０￣（－８）ｐａ·ｌ·ｓ￣（－１）。１６只正式窗在“中国环流器一号”核聚变研究装置上２×８路多结波导阵天线中已经受了１００ｋＷ、１００ｍｓ和１５０ｋＷ、１２０ｍｓ微波功率下的运行考验。

The paper describes the design and fabrication of a rectangular ceramic waveguide window,λ'_g is the wavelength in the waveguide filled with dielectric. The operating frequency is2450 MHz,the VSWR of the model window <1.1, leakage rate <1.3 ×10￣(-8)pa·l·s￣(-1).16 realwindows were connected in the 2×8 multijuntion waveguide array antenna,and operatedreliably,under 100 kW,100 ms and 150 kW,120 ms microwave power conditions,respectively.
