Abstract

The invention belongs to the technical field of microwave sources in vacuum electronic devices, and provides a magnetron structure with modularization characteristics. The magnetron structure comprises n frequency-locking phase-locking circuits and n + 1 magnetrons, wherein n is greater than or equal to 1; each frequency-locking phase-locking circuit comprises two couplers, each coupler is composed of an I-shaped waveguide impedance transformer, a rectangular waveguide, a circular box-shaped waveguide output window and a flange which are sequentially connected, and the two couplers are connected through the flange to form the frequency-locking phase-locking circuit; a gap is formed in the back wall of a magnetron cavity body, and the magnetrons are connected with the I-shaped waveguide impedance transformers of the couplers through the gaps. The magnetron structure adopts the frequency-locking and phase-locking circuits, so that electromagnetic waves of a plurality of magnetrons are frequency-locked and phase-locked to obtain high-power output with the same frequency and phase, power synthesis is further carried out to obtain high power, and the frequency-locking and phase-lockingcircuits are simple in structure and easy to process; the method is expected to have wide application prospects and production value on low-voltage, high-power, arrayed and integrated occasions.

Description

technical field [0001] The invention belongs to the technical field of microwave sources in vacuum electronic devices, and more specifically relates to a magnetron structure with modular characteristics. Background technique [0002] With the development of electronic technology, semiconductor devices have basically replaced electric vacuum devices in low power, low frequency, and low voltage applications, but in high power applications, electric vacuum devices, especially magnetrons, still have an absolute advantage. If the magnetron can provide higher output power at a lower voltage, it will greatly broaden the application range of the magnetron, occupy a dominant position in more civil and military fields, and greatly broaden the application prospects. [0003] At present, the operating voltage of electric vacuum devices is generally high, and the magnetron, as a traditional microwave electric vacuum device, has a relatively low operating voltage, but its output power is ...
