摘要

A novel two-beam oscillator-amplifier based on planar helix slow-wave structure with straight-edge connections is presented. The device combines the operation of both oscillator and amplifier in a single slow-wave structure. the simulation results show that the operating frequency of the oscillator-amplifier tunes from 14.1 GHz to 19.1 GHz when the beam voltage for backward-wave synchronization varies from 3 KV to 8 KV. The output performance of the oscillator-amplifier is compared with that of the conventional backward wave oscillator (BWO) using the same slow-wave structure. The comparison shows that the oscillator-amplifier gives an efficiency improvement of at least two times compared to that of the conventional BWO. Significantly, the oscillator-amplifier preserves the size as well as the tuneable bandwidth of the conventional BWO.
