Abrégé
(EN)
According to various embodiments of the present invention, a portable communication device comprises: an antenna capable of receiving a first signal belonging to a first frequency band corresponding to a first cellular network and a second signal belonging to a second frequency band corresponding to a second cellular network; a first communication circuit electrically connected to the antenna and corresponding to the first cellular network; a second communication circuit electrically connected to the antenna and corresponding to the second cellular network; a distributor electrically connecting the antenna to the first communication circuit and the second communication circuit; a first low-noise amplifier (LNA) connected between the distributor and the first communication circuit; and a second low-noise amplifier (LNA) connected between the distributor and the second communication circuit. The portable communication device may be set such that one of the first communication circuit and the second communication circuit is driven while the other communication circuit is not driven.
