Abstract: A device for suppressing parasitic oscillations in electronic power tubes of coaxial structure. It is constituted by an electrically conductive component of cylindrical form with a flange, containing an odd number of resonant circuits of the RLC type, with distributed constants. Each circuit comprising at least one inductance coupled to at least one capacitor. The latter are respectively constituted by an opening and a slot in said component. The circuits are tuned to the range of frequencies of the parasitic oscillations.

Abstract: The present invention relates to an electronic tube with cylindrical electrodes. In tubes of this kind, where the cathode generally consisting of a wire mesh 1, the space located within same is tightly coupled with the other inter-electrode spaces of the tube. The invention, in order to avert parasitic resonances at the harmonics closest to the operating frequency, which can occur in said space in operation, provides for the arrangement in said space of a certain number of metal sleeves 8, 9 and 10 coaxial with the electrodes, constituting low-inductance coaxial line sections.Application to high-power, short-wave (20 MHz) triodes for transmitting applications.
