ABSTRACT:
A magnetron transition apparatus is provided which permits transmission of a microwave RF signal between a magnetron and an output waveguide. The transition apparatus is connected to the magnetron and receives the RF signal from the magnetron, while maintaining a substantially vacuum environment therein. The transition apparatus further comprises an RF interface between the substantially vacuum environment and a non-vacuum environment within the output waveguide. The microwave RF signal from the magnetron is transmitted through the transition apparatus into the output waveguide. The transition structure comprises an adapter having a first portion of generally circular cross-section and a second portion of generally rectangular cross-section. A conductive loop electrically connected to an anode structure of the magnetron is disposed within the first portion and inductively couples the RF signal from the magnetron into the transition apparatus. The RF interface further comprises an RF transparent window connected between the second portion of the adapter and the output waveguide. The second portion of the adapter has a cross-section consistent with that of the output waveguide.
