The present invention relates to a tunable front-end module and, more specifically, to the tunable front-end module comprising: a duplexer (110) connected to a switch (140) and for separating a transmission signal from a reception signal; a reception chip (120) connected to the switch (140) and for transmitting a signal received from an antenna (200) to a mobile terminal; a transmission chip (130) connected to the switch (140) and for transmitting a signal received from the mobile terminal to the antenna (200); a duplexer (110) connected to one side of a tunable circuit and connected to the transmission chip (130) and the reception chip (120) respectively; the switch (140) selectively connecting the tunable circuit to the reception chip (120) or the transmission chip (130); and the tunable circuit (150) for improving input/output characteristics by connecting to space between the switch (140) and the antenna (200). According to the present invention, the tunable front-end module is able to improve the input/output characteristics of the mobile terminal, to simplify a mobile terminal manufacturing process by reducing the number of modules which are necessary for an RF end of the mobile terminal, and to improve component arrangement efficiency within the mobile terminal.
