A front end module is provided to wire parts of transceicing paths of a multi band into one, thereby reducing a chip size of an RF(Radio Frequency) switch unit and a decoder circuit and reducing costs. A front end module(100) includes an RF(Radio Frequency) switch unit(120), transmitting/receiving filters(140,150) and a decoder unit(130). The RF switch unit switches and selects a path, where two or more paths are wired into one or unwired paths according to a transcieving mode. The transmitting/receiving filter perform filtering for transcieving of a specific RF signal in a multi band. The decoder unit controls the switching operation of the transceiving mode of the RF switching unit.
