A radio reception apparatus includes a reception portion receiving a radio signal, a local oscillation circuit outputting a first local oscillation signal, a local oscillation circuit outputting a second local oscillation signal, a mixer frequency-converting the received radio signal by multiplying the received radio signal by the first local oscillation signal and outputting the frequency-converted signal, a distribution circuit distributing the output signal of the mixer, and a mixer frequency-converting the output signal of the RF mixer by multiplying any one of the signals distributed by the distribution circuit by the second local oscillation signal and outputting the frequency-converted signal.
