CK-622 30kW/915MHz CW Magnetron
Continuous wave magnetron is 33cm, fixed-frequency, full-metal-ceramic structure, and direct thermal pure tungsten cathode, high-power microwave tubes. Electromagnet attached to the magnetic field from the outside to offer water-cooled tube, the cathode leads to air-cooled, microwave energy from the axial antenna output, can directly stimulate a rectangular waveguide acting as the microwave power source used for heating.
