Abstract

The invention discloses a large-span waveband dual-band controllable relativistic backward-wave oscillator. The oscillator comprises an insulating end and an L waveband relativistic backward-wave oscillator connected with the insulating end, wherein positive electrodes are arranged in the insulating end; the positive electrodes are dual-diameter electron beam transmitting negative electrodes; a Ku waveband relativistic backward-wave oscillator is arranged in the cavity of the L waveband relativistic backward-wave oscillator; the L waveband relativistic backward-wave oscillator and the Ku waveband relativistic backward-wave oscillator are fixed into one body through supporting circular rings; and the L waveband relativistic backward-wave oscillator, the Ku waveband relativistic backward-wave oscillator and the negative electrodes are arranged on the same horizontal axial line. According to the oscillator, the structural characteristics of the coaxial relativistic backward-wave oscillator are studied; the coaxial internal conductor in a low-frequency device is taken as a high-frequency-band device; and by adoption of the controllable dual-diameter electron beams, the relativistic backward-wave oscillator can generate the L waveband single-frequency high-power microwave and the Ku waveband single-frequency high-power microwave in sequence, or generate the L waveband dual-frequency high-power microwave and the Ku waveband dual-frequency high-power microwave simultaneously according to needs.

technical field [0001] The patent of the present invention relates to the technical field of high-power microwave devices, in particular to a large-span-band dual-frequency controllable relativistic return wave oscillator. Background technique [0002] In recent years, while pursuing high power, high efficiency, and realizing long pulse and high repetition frequency operation, high-power microwave sources have also shown some other development characteristics, such as the pursuit of a single microwave source device to generate microwaves with multiple frequencies. This type of device can realize the multi-frequency output of a single oscillator, which is an extended research and integrated innovative application of the single-frequency oscillator, and has certain academic value and potential application prospects. The relativistic return wave oscillator has the working characteristics of high power, high efficiency, and is suitable for repeated frequency operation. It is one...

Problems solved by technology

However, the methods for generating dual-frequency high-power microwaves reported at home and abroad all use two separate sets of single-frequency microwave sources in essence. secondly, the space radiation patterns of two or more independently operated microwave sources are relatively complex, which is not conducive to the practical application of high-power microwave; in addition, two independently operated microwave sources will increase the research cost
