Development of a K-band 65-W Space TWT

This paper describes the development of a K-band space traveling-wave tube (TWT) at the Aerospace Information Research Institute, Chinese Academy of Sciences (AIRCAS). This K-band space TWT can produce more than 65-W continuous-wave output power and 60% minimum overall efficiency in the operating frequency band. It achieves a compact size less than 260mm (L) x 60mm (W) x 70mm (H) and weighs less t...
