摘　　要：根据空间通信发展需要对E波段空间行波管输能窗进行研究。窗片的材料选择金刚石,通过菲涅尔理论分析得到无反射盒型输出窗片的关键尺寸,并利用CST软件进行计算和优化,获得适合E波段空间行波管需求的输能窗。通过磁控溅射金属化窗片,封接出气密性良好的输能窗。测试结果表明,该窗在60~87 GHz频段内驻波系数低于1.1。According to the requirement of space communication,the energy transmission window for E-band space traveling wave tube(TWT)is studied.The CVD diamond is selected as window material,and the key dimensions of non-reflective pillbox window are obtained by Fresnel theoretical analysis.Computed and optimized by CST software,an energy transmission window for E-band space TWT is designed.By using magnetron sputtering for window disc metallization,a window with good air tightness is assembled.The cold-test result shows the VSWR of the prototyped pill-box window is below 1.1 during 60~87 GHz.
