Abstract: This paper designs a folded waveguide traveling wave tube which works in 97 GHz-99 GHz. The interaction efficiency of the whole working band is about 3%, and the output power is up to 57 w, therefore the whole tube gain is more than 37 dB. The high-frequency characteristics of the slow wave structure and the amplification performance of the TWT have been investigated.
Keywords: W-band, Folded waveguide, Traveling wave tube.
Acknowledgments: The authors thank the colleagues from the Vacuum Electronics National Laboratory in Beijing for their help in the FWG TWT fabricating.
