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.

In a hyperfrequency generator of the type comprising a source element (5) of negative resistance adjacent to a cylindrical resonant cavity (2) closed at opposite ends by two transverse closure plates (4, 7) movable toward and away from each other for the purpose of tuning over a frequency band;
- the improvement wherein the source element (5) is installed in a notch in a wall of the resonant cavity (2) below an open upper end of the notch and extending between side walls of the notch such that there is a direct physical and electrical coupling between said source element (5) and said side walls of said notch, said source element receiving its bias through a said side wall of said notch.
