CHOKE FILTER OF MAGNETRON

摘要

A choke filter of magnetron is provided to suppress leakage of 3 harmonics and 5 harmonics to the outside and to suppress a high-side band and a low-side band of the 3 harmonics and 5 the harmonics by forming a vertical type choke filter. A choke filter of magnetron includes a vertical choke filter(340) which is attached to a lower side of an A-seal along a height direction of the A-seal. The choke filter is disposed at a lower side of a bent part of the A-seal in order to suppress to leakage of 3 harmonics to the outside. The vertical choke filter includes a disk part attached to an inner surface of the A-seal and a cylinder part(341) formed at a lower end of the disk part. A hollow(343) having a predetermined diameter is formed in a center of the choke filter.
