When the diversity reception is cut, communications with the base station are continued. When it is judged by the judgment section of the mobile communication terminal that a predetermined disconnection requirement for disconnecting diversity reception is satisfied, the gain control section of the digital baseband circuitry 20 reduces the gain of the AGC 14 B contained in the RF receiver circuitry 10 B constituting the disconnection target by a fixed value at fixed times. Diversity reception is cut after the level of the signal output by the AGC 14 B has reached zero.
