Abstract :
The design and cold test of an over-moded 94 GHz Coupled-Cavity Traveling Wave Tube (TWT) with operation in the rectangular TM31 mode is discussed. Lower order modes are suppressed with dielectric loading. Simulations with CST Particle Studio show 31 dB of gain with 300 W peak output power. Cold test results for a 9-cavity structure agree well with HFSS simulations.
