A receiver includes a multiphase mixer that multiplies a received radio
signal by multiphase local signals the number of which is the same as an
integer having a first prime factor and a second prime factor different
from the first prime factor, and generates first multiphase baseband
signals the number of which is the same as the integer, a first
processing circuit that suppresses common modes for first multiphase
signal groups formed by dividing the first multiphase baseband signals
into groups of signals the number of which is the same as the first prime
factor, and generates second multiphase baseband signals, and a second
processing circuit that suppresses common modes for second multiphase
signal groups formed by dividing the second multiphase baseband signals
into groups of signals the number of which is the same as the second
prime factor, and generates third multiphase baseband signals.
