ABSTRACT:
In the present magnetron operating circuit for generating microwave energy, the circuit components of the filter, the transformer and the rectifier are arranged within a shielded housing, in the same manner as the cathode input portion of a magnetron tube. A feed-through capacitor of the filter is arranged in the low voltage line of the transformer and secured to the wall of the housing to prevent undesired radiation. A coil with a ferrite core of the filter is preferably connected to the filament lead of the magnetron tube.
