(EN) ELECTRONIC DEVICE FOR TUNING MODULE FOR PROCESSING RADIO FREQUENCY SIGNAL
(FR) DISPOSITIF ÉLECTRONIQUE PERMETTANT À UN MODULE D'ACCORD DE TRAITER UN SIGNAL RADIOFRÉQUENCE
Abstract
(EN)
Disclosed is an electronic device including a power amplifier (PA) configured to amplify a transmission signal, a matching circuit configured to be connected with the PA and to form a load impedance, a filter configured to be connected with the matching circuit, and a control circuit configured to control a state of at least one of a bias of the PA, the matching circuit, and the filter. The control circuit may identify a network to which the electronic device is connected among a first network and a second network and may operate the matching circuit in one of a first state, a second state, and a third state based on the identified network.

L'invention concerne un dispositif électronique comprenant un amplificateur de puissance (PA) conçu pour amplifier un signal de transmission, un circuit d'adaptation conçu pour être connecté au PA et pour former une impédance de charge, un filtre conçu pour être connecté au circuit d'adaptation, et un circuit de commande conçu pour commander un état d'au moins un élément parmi une polarisation du PA, le circuit d'adaptation et le filtre. Le circuit de commande peut identifier un réseau auquel est connecté le dispositif électronique entre un premier réseau et un second réseau et peut faire fonctionner le circuit d'adaptation dans un état parmi un premier état, un deuxième état et un troisième état sur la base du réseau identifié.
