ABSTRACT:
A coupling device for a microwave tube including a first length of waveguide and a second length of waveguide of rectangular cross-section. The two lengths of waveguide are connected together and have their free ends coupled when operating to a load and to the tube respectively. The large side of the cross-section of the second length of waveguide is equal and parallel to the corresponding side of the first length of waveguide. The small side of the cross-section of the second waveguide is several times smaller than the corresponding side of the first waveguide. Two connected lengths of waveguide form a transition. The first waveguide contains an iris and the coupling device forms an assembly of matched impedance.
