摘要：
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 3x140 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.
