Abstract

The invention discloses a backward wave oscillator (BWO). Compared with a conventional backward-wave oscillator, the BWO has the advantages that a backward-wave amplification structure is added on thebasis of a backward-wave high-frequency structure, the interaction efficiency of electrons and electromagnetic waves is improved under the condition that voltage and current are not increased, and the final output power of the BWO is improved.

Description

technical field [0001] The invention relates to the field of microwave vacuum devices, in particular to a return wave oscillator. Background technique [0002] In the field of microwaves, microwave oscillators are widely used as microwave signal generators in radar, electronic countermeasures, communications and other fields. Microwave oscillation sources generally include vacuum triodes, reflection klystrons, return wave oscillation tubes, and solid-state devices. [0003] The return wave oscillator is generally composed of an electron gun, a high-frequency structure, a collector pole, a magnetic focusing system, an output window, and a cooling system. The return wave oscillator has the advantages of high operating frequency and wide tuning bandwidth, but the output power is generally small. Contents of the invention [0004] The object of the present invention is to provide a return wave oscillator which can greatly increase the output power. [0005] In order to achi...
