Abstract :
The V-band frequency range is a region of the millimeter-wave spectrum that has been developed for inter-satellite communications. A 100 W V-band coupled-cavity traveling-wave tube (CCTWT) is designed using High Frequency Structure Simulator (HFSS) and particle-in-cell (PIC) code in CST Particle Studio. Hot-test simulations show that the designed V-band CCTWT produces saturated output power over 100 W with a gain over 33 dB at the 58-62 GHz frequency range when the beam current is set to 100 mA and the beam voltage is tuned from 15.8 kV to 16.8 kV.
