| Abstract: | This paper designed a folded wavegnide travelling wave tube （TWT） which aimed to meet the system application needs of high power source at 220GHz frequency band. This TWT can generate over 10W output power between 215GHz and 225GHz with gain above 25dB. The folded waveguide high frequency circuit dimensions,beam wave interaction process, electron beam optics system and power coupling window design results were presented in this paper by simulation. The folded wavegnide circuit had been manufactured successfully by UV-LIGA and the manufacturing technics had been discussed. |
