<p>The high-frequency IC according to an embodiment of the invention includes a mixer down-converting the RF signal into an IF signal with a given center frequency lower than that of the RF signal, a first-order low-pass filter with a pass band set narrower than a bandwidth of the IF signal down-converted by the mixer, and an active low-pass filter removing a signal outside the bandwidth of the IF signal.
