随着太赫兹通信技术的发展，D波段折叠波导行波管的研究变得越来越重要。介绍了FWTWT的设计和仿真，包括电子光学系统、折叠式波导慢波结构和蓝宝石药丸盒窗。通过对制造工艺的研究，成功地制造出了样管。在工作负载为100%的实验条件下，电子透过率为97%。连续波输出功率为7.3W，中心频率为140.3 GHz。增益为25.3分贝，3分贝带宽为3 GHz。
As Terahertz communication technology developed, the research for D-band folded waveguide Traveling Wave Tube (FWTWT) has become increasingly important. The design and simulation on the FWTWT was presented, including electron-optical system, Folded Waveguide Slow Wave Structure (FW SWS) and sapphire pill-box window. A prototype tube has been fabricated successfully through manufacturing processing study. In the work duty 100% experiment conditions, the electron transmission ratio is 97%. The continuous wave output power is 7.3W and the center frequency is 140.3GHz. The gain is 25.3dB and 3dB bandwidth is 3GHz.
