Abstract
(EN)
An electronic device is disclosed. The electronic device comprises: an antenna for transmitting and receiving a signal in an RF frequency band; and an RF circuit configured to process the signal in the RF frequency band. The RF circuit comprises: a reception path for transmitting a first signal received through the antenna; a transmission path for transmitting, to the antenna, a second signal outputted from an amplifier; and a coupler for transmitting, to the reception path, at least a part of the second signal acquired from the transmission path. Other various embodiments identified through the specification are possible.
(FR)
La présente invention concerne un dispositif électronique. Le dispositif électronique comprend : une antenne pour émettre et recevoir un signal dans une bande de fréquence RF ; et un circuit RF configuré afin de traiter le signal dans la bande de fréquence RF. Le circuit RF comprend : un trajet de réception pour émettre un premier signal reçu par l'intermédiaire de l'antenne ; un trajet d'émission pour émettre, à l'antenne, un second signal émis par un amplificateur ; et un coupleur pour émettre, au trajet de réception, au moins une partie du second signal acquis à partir du trajet d'émission. Divers autres modes de réalisation identifiés à travers la spécification sont également possibles.
