140 GHz宽带窗的设计及实验
Design and experiment study of 140 GHz broadband window
摘要
输入输出窗是行波管 (TWT)的重要部件, 其性能将直接影响行波管的整体性能指标, 宽带窗的设计一直是其重要发展方向。对 140 GHz行波管的窗结构进行设计, 焊接出样窗部件, 并进行测试。测试结果表明, 宽带窗结构在 130~150 GHz范围内, 反射系数 S11小于-13.6 dB, 传输系数 S21小于-0.8 dB, 验证了宽带窗设计的可行性。
Abstract
Input/output window is one of the important parts of the Traveling Wave Tube(TWT), which directly influences the capability of the TWT. The broadband window is one of the important development directions. Broadband window for 140 GHz TWT is designed, fabricated and tested. Test results show that the S11 parameter is less than-13.6 dB, and the S21 parameter is no more than-0.8 dB when the broadband window is between 130 GHz and 150 GHz, which verifies the feasibility of broadband window design and lays a foundation for the development of broadband TWT.
