Abstract

La présente invention concerne un amplificateur de puissance équipant un terminal de radiocommunications, et plus particulièrement un amplificateur de puissance à haut rendement capable d'amplifier à haut rendement la puissance selon divers niveaux de puissance de sortie, sans utiliser de circuits de commutation en dérivation. L'amplificateur de puissance à haut rendement de l'invention permet d'amplifier divers niveaux de puissance, sans utiliser de circuits de commutation en dérivation, ce qui permet de résoudre les problèmes rencontrés dans le cas des amplificateurs de puissance multimodes selon l'état de la technique, et notamment les pertes de puissance provoquée par les circuits de commutation en dérivation, l'augmentation de taille de l'amplificateur de puissance, et la perte de compétitivité en matière de prix. En l'occurrence, l'amplificateur de puissance à haut rendement de la présente invention réduit la perte de courant continu en mode basse puissance, ce qui permet d'améliorer le rendement de la fonction d'ajout de puissance de l'amplificateur de puissance.
