Abstract
A radio receiver includes a down-converterfor receiving a radio multiplexed signal containing a first signal and a second signal, multiplying the first signal and the second signal by a mixerto thereby down-convert the radio multiplexed signal and generate an intermediate frequency signal. The mixerhas a control section for controlling an operating bias of the mixerin response to a signal strength of at least either one of the first signal or the second signal. Thus, the dynamic range of the mixer can be widened so that stable image characteristics can be obtained over a wide range of transmission distance.
