ABSTRACT:
A magnetron comprises a ceramic stem having a cathode support structure. Sealing metal plates are sealed hermetically to the cathode side of the ceramic stem, closing off hermetically the holes running through the stem for the outer connecting leads. The outer connecting leads are connected electrically to the sealing metal plates. The cathode, which is disposed in the center of the anode, is supported by a pair of cathode support rods. The cathode support rods are fixed to the sealing metal plates. In another embodiment, the end-face of the ceramic stem is formed such that the part of the surface of the stem to which the cylindrical metal container, which constitutes part of the envelope of the stem, is sealed by brazing, and those parts of the surface to which the sealing metal plates are sealed by brazing, are positioned substantially on the same plane.
