This invention relates to a method for amplification of radiocommunication signals by a line (401) of amplifiers (412) associated with a gain controller (413) receiving an amplification set value (Vatt) with constant value (Vfgm) to make a constant gain amplification (FGM), or a variable value (Valc) to make an amplification (ALC) with a constant amplified power (Pout) using a first regulator (406) that can output this variable set value (Valc) starting from a measurement of the amplified power (Pout). According to the invention, such a process is characterized in that, for an amplification mode with constant gain (FGM), a set value transmitted by the first regulator (406) is maintained at a value close to the set value (Vfgm) with constant value (Vfgm).

La présente invention concerne un procédé d'amplification de signaux de radiocommunications par une chaîne (401) d'amplificateurs (412) associée à un contrôleur (413) de gain recevant une consigne (Vatt) d'amplification de valeur constante (Vfgm), pour effectuer une amplification à gain constant (FGM), ou de valeur variable (Valc), pour effectuer une amplification (ALC) à puissance (Pout) amplifiée constante à l'aide d'un premier régulateur (406) pouvant délivrer cette consigne de valeur variable (Valc) à partir d'une mesure de la puissance (Pout) amplifiée. Conformément à l'invention, un tel procédé est caractérisé en ce que, en mode d'amplification à gain constant (FGM), on maintient une consigne transmise par le premier régulateur (406) à une valeur proche de la consigne (Vfgm) de valeur constante (Vfgm).
