CK2091 Magnetron

The CK2091 magnetron is an unpackaged, direct-heated magnetron with a pure tungsten cathode. The magnetic field is provided by an external electromagnet, the anode is cooled by water, the cathode lead-out end and the output end are air-cooled, and the microwave energy is output from the axial antenna. The tube is a fixed frequency continuous wave magnetron with a wavelength of 12 cm, which can directly excite a rectangular waveguide for microwave heating as a power source. It has the characteristics of high efficiency, long life, and high load stability.
