Abstract
The invention relates to a microwave output transition for a high-power electron tube comprising a body () of tubular shape, along a longitudinal axis ZZ', having two ends (), a passage () between the two ends that has internal surfaces for propagating electromagnetic waves, one of the ends (), in the form of a circular cylindrical tube, comprising a conical internal propagation surface () and the other end (), in the form of a tube of rectangular cross section, having two long sides () and two short sides () perpendicular to the long sides, the passage having two plane internal propagation surfaces () parallel to the long sides () and two other plane internal surfaces () parallel to the short sides (). Each of the plane internal propagation surfaces () parallel to the long sides () is joined to the conical internal propagation surface () via a respective curved connecting surface () having bidirectional radii of curvature.
