Abstract:
1. A receiving circuit for performing reception of a plurality of band signals and suppression of blockers that remain in the plurality of band signals being received and converted in frequency, said receiving circuit comprising: a first low-pass filter that has a first pole position and that is configured to suppress blockers remaining in a received signal by the first pole position; a second low-pass filter that has a second pole position different from the first pole position and that is configured to suppress blockers remaining in a signal that has passed through said first low-pass filter by the second pole position; and a switch that is configured to switch on/off an input-output path including said first and second low-pass filters so that the received signal passes through said first low-pass filter without passing through said second low-pass filter in case of receiving a first band signal while the received signal passes through both said first and second low-pass filters in case of receiving a second band signal different from the first band signal.
