Abstract :
The design of a Ka-band three-beam cascaded serpentine travelling-wave tube (TWT) amplifier is presented. Simulations predict that a peak power of 3.5 kW with saturated gain of 16 dB and an instantaneous bandwidth of 30% can be achieved in a circuit length of ≤ 4.5 cm driven by three 20 kV beams with 0.5-A each. A plan for a proof-of-principle experiment will also be discussed.
