Wideband power combining of four W-band microfabricated traveling-wave tubes (TWTs) is presented. The proposed TWTs are based on a planar helix slow-wave structure (SWS) with straight-edge connections (PH-SEC) that can be microfabricated with stripline input-output feed. A novel 1:4 WR-10 waveguide-...
