MAGNETRON HAVING CHOKE FILTER

摘要

A magnetron having a choke filter is provided to suppress bad influence due to radio frequencies by preventing the leakage of the radio frequency generated therefrom. A yoke(301) includes a constant internal space which is formed by coupling an upper yoke(301a) and a lower yoke(301b). An upper magnet and a lower magnet(322) are installed in the internal space. The upper magnet and the lower magnet are fixed to the upper yoke and the lower yoke along a width direction of the yoke. An anode cylinder is disposed between the upper magnet and the lower magnet in order to generate radio frequency energy. An upper pole piece and a lower pole piece are arranged at an upper opening and a lower opening of the anode cylinder. An A-room having a shape of cylinder is disposed at an upper side of the upper pole piece in order to shield leakage of 5 harmonics. A choke filter is boned with the inner plate of the A-room and includes a coupling slot part for shielding leakage of 3 harmonics.
