E频段(71-76 GHz和81-86 GHz)已用于具有几千兆位/秒数据速率的点对点链路。前端由固态放大器供电，输出功率约为2-3W。这种输出功率值限制了范围和频谱效率，并且必须由高增益天线来补偿。几十瓦的可用性将允许更高的频谱效率和更远的射程，并使用更低增益的天线来实现多波束和区域覆盖。本文报道了第一个基于双波纹波导的E波段行波管的设计和初步制作。一个测试短相互作用结构行波管正在组装阶段，作为概念验证，输出功率约为2W。最终的行波管设计为提供约70 W功率和约40分贝增益。
E-band (71 – 76 GHz and 81 – 86 GHz) is already used for point to point links with a few Gigabit/second data rate. Front-ends are powered by solid state amplifiers with about 2 – 3 W output power. This output power values limit range and spectral efficiency and have to be compensated by high gain antennas. The availability of tens of Watt would allow higher spectral efficiency and long range, and the use of lower gain antennas for multibeam and area coverage. This paper reports the design and the initial fabrication of the first ever E-band Traveling Wave Tube (TWT) based on the double corrugated waveguide. A test short interaction structure TWT is in assembly phase as proof of concept with about 2 W output power. The final TWT is designed to provide about 70 W power and about 40 dB gain.
