Abstract

The invention discloses an axial cascade relativistic magnetron based on frequency locking and phase locking of a full-cavity coupling structure, and belongs to the technical field of microwaves. The magnetron comprises a plurality of high-frequency systems which have the same structure and are axially cascaded; an annular columnar isolation structure is arranged between the adjacent high-frequency systems; a full-cavity coupling structure shell is arranged on the outer side of the anode shell; an annular columnar cavity between the full-cavity coupling structure shell and the anode shell is divided into four fan-shaped waveguide cavities with the same size through four fan-shaped insertion pieces; linear transition structures are arranged at two ends of the fan-shaped waveguide cavity, and the other ends of the linear transition structures are connected with the rectangular waveguide; energy in the resonant cavity is coupled to the four fan-shaped waveguide cavities through the coupling gaps and finally output from the eight rectangular waveguides. Electromagnetic fields in the adjacent high-frequency system resonant cavities are coupled through the full-cavity coupling structures, and the cascade phase locking effect is enhanced; and through full-cavity extraction and multi-port axial output, the radial space compactness is improved, and the mode purity and the working stability are also improved.
