W-band sheet beam staggered double grating traveling wave tube with simplified input/output structure

摘要

Using a simplified input/output (I/O) structure, a sheet beam traveling wave tube is designed, producing 644W at 94 GHz with a corresponding gain of 38.1 dB. And the 3-dB bandwidth is more than 12.7%. A uniform longitudinal magnetic field of 1 T was used in the PIC simulation. CST simulation results of the S parameters of the I/O structure and the port signals of the PIC model in 50ns are shown in the paper.
