Abstract

La présente invention concerne un système de radiofréquence et un dispositif électronique, comprenant un émetteur-récepteur de radiofréquence, un circuit de traitement de radiofréquence, un module commutateur de transfert, une première antenne et une seconde antenne ; le circuit de traitement de radiofréquence comprend un premier module d'émission, un second module d'émission, un module de réception primaire, un module de réception en diversité, un premier multiplexeur, un second multiplexeur et un coupleur directionnel ; le système de radiofréquence est utilisé pour mettre en œuvre une communication à double connectivité EN-CC d'une première bande basse-fréquence et d'une seconde bande basse-fréquence. En pouvant utiliser deux multiplexeurs et une conception de circuit de radiofréquence combinée, et à l'aide de dispositifs spéciaux pour obtenir une conception de combinaison d'antennes, deux antennes peuvent réaliser une mise en réseau non autonome à double bande basse-fréquence, ce qui permet d'augmenter considérablement la facilité d'utilisation d'une mise en réseau non autonome à double bande basse-fréquence dans des dispositifs électroniques.
