Abstract：

A　detailed　development　of　a　　$G$　-band　continuous-wave　(CW)　traveling-wave　tube　(TWT)　with　a　160-GHz　$\cdot$　W　product　of　bandwidth　power　is　reported　in　the　present　work,　in　which　the　electron　optics　system　(EOS),　the　tapered　phase　velocity　folded　waveguide　(TPVFW)　slow　wave　structure　(SWS),　the　modified　pill-box　window　(MPBW),　and　experimental　results　are　described.　The　prototype　of　the　proposed　TWT　is　fabricated　with　optimized　structural　parameters　obtained　by　particle-in-cell　(PIC)　simulations.　Moreover,　the　experimental　results　show　that　TWT　with　27-W　output　power　at　the　frequency　of　220　GHz　at　100%　duty　cycle　is　obtained　at　the　operation　voltage　of　17.1　kV　and　the　current　of　62　mA.　The　proposed　　$G$　-band　TWT　will　have　broad　applications　in　far-distance　high-resolution　imaging　and　large　communications　capacity.　IEEE
