Abstract
An automatic gain correction circuit for radiofrequency signals applies notably to the regulation of the amplification of signals for satellite radionavigation. The automatic gain correction circuit is able to receive an input radiofrequency signal and to deliver an output radiofrequency signal of which a mean amplitude is slaved to a setpoint. It comprises means for modifying the setpoint as a function of the mean amplitude of the input signal between a minimum setpoint value and a maximum setpoint value, the minimum setpoint value corresponding to a first mean amplitude of the input signal and the maximum setpoint value corresponding to a second mean amplitude of the input signal, the first mean amplitude being lower than the second mean amplitude.
