Abstract

L'invention concerne un dispositif d'émission-réception radio-fréquence double mode, un dispositif de filtrage et un terminal double mode. Le dispositif d'émission-réception radio-fréquence double mode comprend au moins un amplificateur à faible bruit (LNA) conçu pour la même bande de fréquence qu'un signal de premier mode et qu'un signal de second mode. Le LNA est utilisé pour recevoir des signaux des bandes de fréquence correspondantes du signal de premier mode et du signal de second mode par multiplexage par répartition dans le temps, amplifier les signaux reçus, puis les émettre. Etant donné que le LNA est un LNA de multiplexage, le nombre de LNA dans le dispositif d'émission-réception radio-fréquence double mode est réduit, le dispositif d'émission-réception radio-fréquence double mode peut être intégré dans une plus grande mesure, augmentant l'espace de configuration, de sorte que le degré d'intégration d'un terminal double mode comprenant le dispositif d'émission-réception radio-fréquence double mode est supérieur, ce qui est plus avantageux pour mettre en œuvre une miniaturisation des terminaux.
