A mobile communication terminal is provided to output a reference frequency signal to a short-range communication module and a wireless communication module for transceiving a wireless signal with a base station, by using one oscillator only, thereby avoiding unnecessary current consumption. A mobile communication terminal comprises as follows. The first AND circuit(161) processes an AND operation by receiving a reference frequency usage request signal from a short-range communicator(15) and a short-range communication unit operation signal from a controller(10). An OR circuit(162) processes an OR operation by receiving a reference frequency usage request signal from the controller and an output signal from the first AND circuit. An oscillator(163) generates a reference frequency signal to output the generated signal to a wireless communication unit(13) and the short-range communication unit. The second AND circuit(164) receives an output signal from the first AND circuit and the reference frequency signal from the oscillator to process an AND operation, and outputs the reference frequency signal to the short-range communication unit.
