Abstract

The invention discloses a double-electron-beam relativistic return-wave tube capable of directly outputting dual-frequency microwaves, which belongs to the technical field of high-power microwave devices. The present invention adopts concentric double-ring cathodes and first and second high-frequency structures connected together. The first high-frequency structure includes an outer conductor pre-modulation cavity, an outer conductor slow-wave structure and an outer electron beam collector. The second high-frequency structure It includes an inner conductor pre-modulation cavity, an inner conductor slow wave structure, a drift section and an inner electron beam collector. The two columns of electron beams emitted by the concentric double-ring cathodes have beam effects on the inner and outer conductor slow-wave structures respectively, and generate two different frequencies of TM01 mode electromagnetic waves, and realize the natural synthesis in the entire device to obtain stable beat waves . Compared with the existing dual-frequency coaxial relativistic return wave tube, the inner and outer conductors in the present invention are directly connected together, without additional design of supporting connecting rods between the inner and outer conductors, and the device structure is simple , easy to process.

Description

technical field [0001] The invention belongs to the technical field of high-power microwave devices, and in particular relates to a relativistic return wave tube with dual electron beams that can directly output dual-frequency microwaves. Background technique [0002] In recent years, a lot of research has been carried out on high-power microwave devices in terms of high power, high efficiency, high repetition frequency, long pulse, and low magnetic field. research direction. The beat waves generated by dual-frequency high-power microwave devices can be used to attack electronic systems and various communication systems. The instantaneous power of the beat wave is high, which can effectively increase the operating distance. In addition, the formed beat wave spectrum is rich in components, and the high-frequency carrier can be used to transmit low-frequency microwaves. The diffraction effect of the low-frequency signal is conducive to the backdoor coupling, which can effecti...
