Abstract:
1. A method for amplifying radiocommunication signals by a string of amplifiers associated with a gain controller receiving an amplification setpoint (V att ) of constant value (V fgm ), in order to produce an amplification with constant gain (FGM) or with variable value (V alc ), in order to produce an amplification (ALC) with constant amplified power (P out ) with the aid of a first regulator that is able to deliver this variable value setpoint (V alc ) based on a measurement of the amplified power (P out ), wherein a second regulator regulates the first regulator, in constant gain amplification mode (FGM) so that the first regulator supplies a setpoint at a value close to the constant value setpoint (V fgm ) by carrying out a closed-loop control of the setpoint of variable value (V alc ) transmitted by the first regulator based on the setpoint of constant value V fgm .
