There is provided an intermodulation (IMD) control device and method in a mobile communication system. In the IMD control device, an LNA performs low noise amplification on an input RF signal, a first switch is connected to the LNA in parallel, for switching according to a first control signal received for IMD control, a frequency converter down-converts the output of the LNA to an IF signal, an IF amplifier amplifies the IF signal, a second switch is connected in parallel to the IF amplifier, for switching according to a second IMD control signal received for IMD control, and a controller generates the IMD control signals at voltage levels determined according to an RSSI and an energy to noise ratio.
