Hyperfrequency wave generator device comprising a plurality of magnetrons

The hyperfrequency wave generator device according to the invention comprises a plurality of magnetrons, each magnetron comprising: a cathode, and an anode, surrounding the cathode and comprising an inner surface defining a plurality of resonant cavities distributed along its periphery. The generator device also comprises at least one waveguide, each waveguide extending from the anode of a magnetron toward the outside of the magnetron. The plurality of resonant cavities of each magnetron comprises a plurality of resonant connecting cavities, or at least one resonant connecting cavity and at least one resonant output cavity. Each resonant connecting cavity of each magnetron is identical each resonant connecting cavity and, if the magnetron comprises at least one output cavity, to each resonant output cavity of the magnetron.
