Magnetron

CK-2091 continuous-wave magnetron is a metal-ceramic construction microwave tube with fixed frequency. The operating magnetic field is provided by external electromagnet. The microwave energy is radiated by it’s axial probe which is inserted to the launching section. This tube is used for microwave heating. Please read carefully this data before putting the magnetron into operation.
