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.
Claims16
A device for suppressing parasitic oscillations in an electronic tube having a coaxial structure, comprising a component made of a material which is electrically conductive in the frequency range of said parasitic oscillations and substantially in the form of a cylinder with a flange, said component carrying a plurality of resonance circuits each of RLC type and incorporating at least one inductance constituted by an opening in said component coupled to at least one capacitor constituted by a slot in said component, said resonant circuits being tuned to the frequency range of said parasitic oscillations, the surface of said flange and the angle said flange makes with the surface of said cylinder being such that the impedance variation produced in the tube by said component is minimised.
