A mobile communication apparatus includes an amplification circuit, a power supply section, a signal conversion section, a detector, and a control section. The amplification circuit amplifies a received radio signal to output an RF-amplified signal. The power supply section supplies power to the RF amplification circuit. The signal conversion section converts one of the RF-amplified signal and the received radio signal from the RF amplification circuit into an intermediate frequency signal. The detector detects the IF signal output from the signal conversion section. The control section detects the reception sensitivity of the received radio signal on the basis of the RF-amplified signal from the RF amplification circuit, and controls the supply of power from the power supply section to the RF amplification circuit and performs bypass control on the RF amplification circuit on the basis of the detected reception sensitivity and a predetermined reception sensitivity. |
