Development of Ku band miniature TWT
This paper describes the development of miniature Ku-band pulsed helix traveling wave tube(VE3306) within 2GHz bandwidth. The peak power reached more than 450W and overall efficiency was 42% with 30% pulsed duty cycle. The miniature TWT can be used as the transmitter of T/R module and booster of MPM(Microwave Power Module).
