Abstract

L'invention propose un procédé et un dispositif de modulation de l'amplitude d'un signal radiofréquence à l'aide d'un amplificateur de puissance radiofréquence à gain variable (PA), permettant d'asservir la puissance du signal de sortie (G) de l'amplificateur (PA) en générant un signal d'erreur (U) entre un signal de modulation d'amplitude (C) et un signal (L) représentatif de la puissance du signal de sortie (G) de l'amplificateur (PA), à partir duquel un signal de commande (F) du gain de l'amplificateur (PA) est généré, de surveiller une éventuelle saturation de l'amplificateur (PA) en comparant les phases relatives du signal d'erreur (U) et du signal de modulation d'amplitude (C), et, en cas de saturation de l'amplificateur (PA), générer un signal de correction (W) permettant d'abaisser le point de fonctionnement de l'amplificateur (PA). Application à un émetteur de station mobile ou de station fixe d'un système de radiocommunications.
