Coaxial line frequency-locking and phase-locking structure and magnetron array system formed by coaxial line frequency-locking and phase-locking structure

The invention belongs to the technical field of microwave sources in vacuum electronic devices, and particularly relates to a coaxial line frequency-locking and phase-locking structure and a magnetron array system formed by the coaxial line frequency-locking and phase-locking structure, which comprises a magnetron provided with a coaxial cable and at least one coaxial energy coupler, the coaxial energy couplers of two adjacent magnetrons are connected through a coaxial cable between the two adjacent magnetrons; the N + 1 magnetrons at least comprise N coaxial cables, and the length, impedance, power capacity and other electrical parameters of the cables can be flexibly selected; ngt; 1 is also a plurality. Efficient frequency locking and phase locking are introduced between the magnetrons, so that phases of output power between the tubes are coherent, and the problem of power capacity limitation of a single tube is solved by using a large number of magnetrons to form an array; the problem that an array is fix
