A receiver circuit includes a first mixer that performs frequency conversion on a first signal containing a first frequency entered from outside to output the resulting frequency-converted first signal, and a first selector that selects one out of an output signal of the first mixer and a second signal containing a second frequency entered from outside. A filter removes a pre-set frequency band of the signal selected by the first selector, and a second selector selects between outputting the signal removed of the frequency band to outside and outputting the signal to a subsequent side circuit. A second mixer performs frequency conversion of the signal output from the second selector to output the resulting frequency-converted signal. The second mixer is the subsequent side circuit. The second frequency has a carrier frequency of a radio signal. |
