Abstract

PURPOSE:To reduce power consumption by providing a control means to stop the supply of a driving current to a predesignated reception function circuit so as to prevent the useless current consumption. CONSTITUTION:A reception level detection circuit 2 detects an intermediate frequency signal coming from a frequency conversion circuit 1 corresponding to the reception level of a reception signal and the detection output of the reception level detection circuit 2 is supplied to a comparator input terminal of a comparator 3. When the input voltage is smaller than the reference voltage, the comparator 3 outputs a control signal representing it that the radio receiver is in the signal waiting state and a switching circuit 5 interrupts the connection between the power supply 6 and the intermediate frequency amplifier circuit 7, the detection circuit 8 and the low frequency amplifier circuit 9. Thus, the supply of the driving current to each reception function circuit is interrupted and the current consumption for the useless reception in the signal waiting state is prevented.
