Abstract :
The design of a V-band helix-folded waveguide (H-FWG) cascaded traveling wave tube (TWT) is presented. In this cascaded structure, a high-gain helix TWT is carefully designed as a first stage amplifier followed by a FWG TWT to obtain high power. Simulations predict that a peak power of 800W with saturated gain of 55 dB from 55GHz to 60 GHz can be achieved.
