Abstract: A front end module supporting a plurality of frequency bands and an electronic device includes a plurality of duplexers, a first switch configured to connect any one of the plurality of duplexers to an antenna, a second switch configured to connect a first port, to which a Tx signal of a first communication or a Tx signal of a second communication is input, to any one of Tx ports of the plurality of duplexers, and to connect a second port, from which a Rx signal of the second communication is output, to one of the Tx ports of the plurality of duplexers. According to certain embodiments, the number of switches occupying a large space can be minimized, and thus a space occupied by the front end module supporting device to device (D2D) communication can be reduced.
