An interface method for gain control and a device therefor are provided to enable a mobile terminal of a mobile communication system to offer an effective interface between an RFIC(Radio Frequency Integrated Circuit) and a digital IC, thus a simple and stable signal connection can be ensured without applying a burden to a digital unit of the RFIC. A signal measurer(204) measures the strength of a signal received from an RFIC(202), and generates a control signal for controlling a gain so that the strength of the received signal becomes equal to predetermined signal strength, if the strength of the received signal is not the same as the predetermined signal strength. A control signal generator(206) receives the control signal to generate an increase/decrease select signal for instructing an increase or a decrease of signal strength received from the RFIC(202) and to generate a clock for instructing a width for increasing or decreasing the strength of the received signal.
