Output component structure for magnetron

Abstract

This invention relates to a magnetron output unit increasing the attenuation ability of the third high-key wave band by adjusting the length of an exhaust tube of the magnetron including: the said magnetron output part includes a support, a ceramic antenna, an exhaust tube, and antenna supply line, among which, the said support fixes the antenna cover, the ceramic antenna joins with the support, the exhaust tube is on the support with its upper end at the bottom of the cover and the bottom fixed in certain distance with the top of the ceramic antenna, the said supply line is assembled on the inside wall of the exhausted tube for radiating the high-key wave energy transferred to the said anode to outside to meet EMI.

Description

technical field [0001] The present invention relates to a magnetron, and furthermore, relates to a structure of an output part of the magnetron. Background technique [0002] Generally, the magnetron applies power to the filament (filament) of the cathode terminal of the above-mentioned magnetron, so that the filament is heated to release thermal electrons, and the magnetic field formed by the magnet (magnet) combined inside and perpendicular to the above-mentioned In the electric field of the magnetic field, the thermal electrons rotate and generate microwaves, and the generated microwaves are emitted to the outside. [0003] Refer below figure 1 The structure of the above-mentioned conventional magnetron will be described. [0004] figure 1 A cross-sectional view of a prior art magnetron is shown. [0005] Such as figure 1 As shown, the magnetron generally includes a series cathode (cathode) 8, an anode (anode) 5, an action space 6, an upper yoke 16 and a lower yoke 1...
