A receiving apparatus includes a first circuit to receive a radio wave of a first frequency band from a tuning circuit, a second circuit, including an amplifier to receive a radio wave of a second frequency band lower in frequency than the first frequency band, and a generating circuit to generate a tuning voltage for the tuning circuit in a first state in which the radio wave of the first frequency band is received, and a bias voltage for the amplifier in a second state in which the radio wave of the second frequency band is received. The generating circuit includes a voltage generator to generate and output the tuning voltage and the bias voltage to an output route, and a switching circuit to switch the output route to couple to the amplifier in the second state.
