Abstract

L'invention concerne un module d'amplification de puissance, un module frontal radiofréquence, un émetteur-récepteur radiofréquence multimode, un terminal multimode et un procédé permettant à un terminal multimode d'envoyer des signaux. Le module d'amplification de puissance comprend un module de commande et un amplificateur à basse fréquence et un amplificateur à haute fréquence connectés au module de commande. Le module de commande est utilisé pour envoyer un signal d'indication de mode de fonctionnement à l'amplificateur à basse fréquence ou à l'amplificateur à haute fréquence conformément à un signal de commande provenant d'une puce de bande de base. L'amplificateur à basse fréquence est utilisé pour recevoir un signal d'émission à basse fréquence et le signal d'indication de mode de fonctionnement envoyé par le module de commande et pour amplifier le signal d'émission à basse fréquence conformément au mode de fonctionnement indiqué par le signal d'indication de mode de fonctionnement et pour fournir ce dernier en sortie. L'amplificateur à haute fréquence est utilisé pour recevoir un signal d'émission à haute fréquence et le signal d'indication de mode de fonctionnement envoyé par le module de commande et pour amplifier le signal d'émission à haute fréquence en fonction du mode de fonctionnement indiqué par le signal d'indication de mode de fonctionnement et pour fournir en sortie ce dernier. Un terminal multimode comportant le module d'amplification de puissance mentionné ci-dessus permet de réduire efficacement la superficie occupée par une carte de circuit imprimé (PCB).
