A capacitor 1 includes a conductive tube 2, coveted by insulating material 3 and a layer of conductive material 4 located at the central part of the tube 2. The geometry presents a low inherent inductance and a continuous, distributed conductance. The capacitor 1 may be used as a bypass capacitor in an IOT amplifier to reduce stray and leakage high frequency radiation, in one amplifier being located within the inner wall 11 of an annular input cavity 10.
