ABSTRACT:
A filter for preventing an electromagnetic wave from leaking from a cathode line of a magnetron comprises an inductance element connected in series to the cathode line and a reactance element of a coaxial structure including a portion of the cathode line as a center conductor, a surrounding dielectric material and a surrounding metal conductor. A cup-shaped conductor is arranged around the reactance element to form a parallel inductance component to the cathode line.
