摘要

研制了一种用于0.14THz折叠波导行波管的蓝宝石片宽带药盒窗。冷测结果表明，在0.13THz-0.15THz范围内，窗口的衰减约为0.7dB。采用背靠背的方法，对包含丸盒和锥形波导的射频耦合系统进行了测试。结果表明，该方法的驻波比小于1.2，满足0.14THz折叠波导行波管的实际要求。

Investigation of 0.14THz pill-box window for folded waveguide TWT

A broadband pill-box window with sapphire piece for 0.14THz folded waveguide traveling wave tube is manufactured. Cold-test result shows the attenuation of the window is about 0.7dB during 0.13THz-0.15THz. Using the back-to-back method, the RF coupling system including pill-box and taper waveguide is test. The result shows that the VSWR is less than 1.2, which meets the practical requirements in 0.14THz folded waveguide TWT.
