In this paper, the design and optimization of a V-band helix TWT is carried out and prototype tubes have been assembled. The test results show that the output power of the TWT is over 15W with the overall efficiency of over 14.5% and a gain of over 43dB. The beam transmission experiment shows that a transmission ratio is over 97%.
A Ku-150W space TWT of electronic efficiency(>23.8%), overall efficiency (> 58%j\ phase shifl(<45deg) for frequency fo±0.5GHz has been designed and developed for satellite communication system. This paper presents design and development.
