Magnetron

摘要

A magnetron is configured so that an antenna lead 17 connected to a desired position of an anode segment 2 passes through a magnetic pole piece 7 and a metal cylinder 8 so as not to make contact therewith and is connected to the output portion of the magnetron, and so that the electrical length L 1 of this antenna lead 17 between the opening end of a third harmonic restraint choke 15 and the connection portion of the anode segment 2 is 1/2 of the wavelength (lambda) of the third harmonic, thereby restraining the third harmonic and the side bands of the third harmonic.
