V-band traveling wave tube design and analysis

Summary form only given. The need for millimeter-wave amplification and its application has been grown rapidly in conjunction with millimeter-wave solid state device development and advancement in microfabrication techniques. This paper present design and analysis of a V-band millimeter-wave traveling wave tube amplifier. Two different slow wave structures (SWS), tunneladder and folded waveguide, are thoroughly analyzed using 3D electromagnetic field simulators. Design parameters including dispersion relation and interaction impedance are introduced. Output performance prediction is made by small and large signal analysis.
