Abstract
(EN)
Provided is an electronic device operating in multiple bands according to the present invention. The electronic device comprises a dual band filter configured to pass all received signals of a first frequency band and/or a second frequency band, and a low noise amplification unit (LNA) for amplifying a first signal in the first frequency band and a second signal in the second frequency band, and performing impedance matching on at least one of the first frequency band and the second frequency band. In addition, the electronic device further includes a modem for controlling an impedance matching unit in a receiving amplifier (LNA) so that the impedance matching is performed in one of the first frequency band (DL band) and the second frequency band (SDL band), thereby improving reception performance by dynamically using different frequency bands without increasing circuit complexity.

La présente invention concerne un dispositif électronique fonctionnant dans de multiples bandes. Le dispositif électronique comprend un filtre à double bande configuré pour laisser passer tous les signaux reçus d’une première bande de fréquences et/ou d’une seconde bande de fréquences, et une unité d’amplification à faible bruit (LNA) pour amplifier un premier signal dans la première bande de fréquences et un second signal dans la seconde bande de fréquences, et réaliser une adaptation d’impédance sur la première bande de fréquences et/ou sur la seconde bande de fréquences. De plus, le dispositif électronique comprend en outre un modem pour commander une unité d’adaptation d’impédance dans un amplificateur de réception (LNA) de sorte que l’adaptation d’impédance est réalisée dans la première bande de fréquences (bande DL) ou dans la seconde bande de fréquences (bande SDL), ce qui améliore la performance de réception par une utilisation dynamique de différentes bandes de fréquences sans augmenter la complexité des circuits.
