ABSTRACT:
A magnetron has a filter circuit inserted in a feeder line to a cathode electrode included in a high frequency generator and comprised of choke coils and a capacitor connected in series, in order to suppress leakage of unwanted high frequency components from the cathode electrode. At least one of the choke coils has an air-core coarse coil winding close to the cathode electrode which has at least two turns and a remainder of fine coil winding wound about a ferrite core, so that burning of the choke coil and overheating of the ferrite core can readily be prevented without imparing the function to suppress unwanted high frequency component leakage.
