The RF structure development of a W-band folded waveguide TWT (traveling wave tube) is presented with special emphasis on fabrication techniques. After a short overview of the RF parameters first results on inline milling are given. Both a scaled-down structure at X-band and different W-band structures were fabricated by milling and measured. Results compare well with simulations. Keywords: traveling wave tube, folded waveguide, vacuum electronics
