According to one aspect of the invention, there is proposed a capacitive radiofrequency MicroElectroMechanical System or capacitive RF MEMS comprising a metallic membrane suspended above an RF transmission line and resting on ground planes, and exhibiting a lower face, an upper face opposite to the lower face and a first layer comprising a refractory metallic material at least partially covering the upper face of the membrane so as to prevent the heating of the membrane.

Capacitive RF MEMS intended for high-power applications

A passive radiofrequency microelectronic components for an integrated circuit which includes a dielectric substrate and at least one metal conductive layer positioned on said substrate. The conductive layer including at least one first metal conductive portion and a second metal conductive portion separated by an insulation. A microelectronic component according to the invention includes at least one graphene layer positioned so that a radiofrequency or hyperfrequency signal crosses said at least one graphene layer when it is transmitted between said first metal conductive portion and said second metal conductive portion, said graphene layer being able, when it is subject to an electric potential, to transmit said radiofrequency or hyperfrequency signal along a first direction and to attenuate said radiofrequency or hyperfrequency signal along a second direction opposite to said first direction.
