Abstract

Amplifying device for amplifying an amplitude modulated high frequency signal, said device comprising an amplifying stage that delivers the amplified signal, characterized in that it comprises a circuit that includes a resistance and a parallel capacitor, coupled to said amplifying stage to deliver a signal auxiliary representative of the mean value of the amplified high frequency signal, and means for coupling said circuit to said amplifying device in order to vary the gain.
