Abstract
A hyperfrequency generator comprising a source element (5) of negative resistance adjacent to a cylindrical resonant cavity (2) closed at opposite ends by two transversal closure plates (4, 7) for the purpose of tuning over a frequency band. The source element (5) is installed directly in the resonant cavity (2) such that there is a direct coupling between the source element (5) and the resonant cavity (2). One of the closure plates (7) is movable toward and away from the other for rough tuning.
