Abstract

Selon divers modes de réalisation de la présente divulgation, un dispositif électronique peut comprendre une antenne, ainsi qu'un émetteur-récepteur raccordé à l'antenne et comprenant un circuit d'émission et un circuit de réception de retour. Dans un mode de réalisation, le dispositif électronique peut comprendre un circuit de traitement de signal sans fil disposé entre l'antenne et l'émetteur-récepteur. Dans un mode de réalisation, le dispositif électronique peut comprendre un coupleur disposé entre un premier circuit d'amplification intégré dans le circuit d'émission de l'émetteur-récepteur et un second circuit d'amplification du circuit de traitement de signal sans fil. Dans un mode de réalisation, le dispositif électronique peut comprendre un circuit de commutation conçu pour raccorder électriquement le circuit de réception de retour de l'émetteur-récepteur au coupleur. Dans un mode de réalisation, le dispositif électronique peut comprendre un processeur fonctionnellement connecté à l'antenne, à l'émetteur-récepteur, au circuit de traitement de signal sans fil, au coupleur et au circuit de commutation. Dans un mode de réalisation, le processeur peut détecter, au moyen du coupleur, un signal sans fil transmis au second circuit d'amplification du circuit de traitement de signal sans fil par l'intermédiaire du premier circuit d'amplification de l'émetteur-récepteur. Dans un mode de réalisation, le processeur peut commander le circuit de commutation afin d'amener le coupleur et le circuit de réception de retour de l'émetteur-récepteur à être raccordés électriquement l'un à l'autre de façon à recevoir, par l'intermédiaire du circuit de réception de retour de l'émetteur-récepteur, un signal sans fil détecté par le coupleur. Dans un mode de réalisation, le processeur peut commander le second circuit d'amplification de façon à ne pas effectuer une opération d'amplification si le signal sans fil reçu ne se situe pas dans une première bande de fréquences mais dans une seconde bande de fréquences différente de la première. En plus des divers modes de réalisation divulgués dans le présent document, divers autres modes de réalisation sont également possibles.
