Abstract

A traveling wave tube (TWT) based on carbon nanotube (CNT) cold cathode is theoretically researched in this paper. A magnetic injection electron gun and helix slow-wave structure is adopted in the TWT. Simulation results show that the maximum output power of the CNT TWT can reach 54 W at 9.4 GHz with an input power of 50 mW, corresponding to the maximum gain of 30 dB, when the gyrating electron beam voltage and current are 19.2 kV and 50 mA, respectively. And the 3 dB bandwidth of the CNT TWT is about 4 GHz.
