BVERI开发了70W e波段行波管（TWT），以满足未来高数据速率无线通信的需求。行波管是一种周期性的永磁聚焦折叠波导管。它可以在81-86GHz范围内产生超过75W的连续波饱和输出功率。采用单级降压集热器，效率可达16.7%以上。文中还给出了非线性相移和三阶互调的测试结果。
BVERI has developed a 70W E-band travelling wave tube (TWT) to meet the demands of future high data rate wireless communication. The TWT is a periodic permanent magnet focused folded waveguide tube. It can produce over 75W continuous wave saturated output power over the range of 81-86GHz. With a single stage depressed collector, it can realize an efficiency over 16.7%. The test results of nonlinear phase shift and third order intermodulation of the tube are also presented in this paper.
