Abstract
The design of a wideband W-Band travelling wave tube using the staggered double-vane slow-wave structure combined with plan alignment three pencil beams is described in this paper. A more simple new type input and output coupler is brought forward with high transmission characteristics and short beam-wave interaction length for the easily beam transport and structures fabrication later. Particle in cell (PIC) simulations predict that when the beam voltage is of 22kV and beam current of 3×140 mA respectively, the travelling wave tube can produce over 2.25 kW of peak power within the total length of 70mm, also with a corresponding gain of 43 dB and an electronic efficiency of 12% at 94 GHz. And the 3 dB bandwidth can be achieved about 15 GHz.
