STRUCTURE OF MAGNETRON OSCILLATOR'S CATHODE ASSEMBLY

摘要

A structure of magnetron oscillators cathode assembly is provided to reduce the radiation of a microwave noise to the outside by controlling the thickness and external diameter of the feeder wire. A cathode filament is positioned at the central axis of anode, and a feed wire supplies power the cathode filament. In the feed line, a predetermined period and the other period have different thickness and diameter. The feed line prevents a microwave from being leaked to the outside due to supplying power. The predetermined period is lambda/8 <= L0 <= lambda/2, lambda is a wavelength.
