Abstract
To improve the degree of removal of unwanted component signals with a small area while eliminating the need for a high-frequency signal source. IF band simulated image signals IM-I, IM-Q output from an IF band simulated image signal generating unit () are input to a quadrature mixer () through a path switch (). The signals IM-I and IM-Q which are fed through and output from the quadrature mixer () are output from a complex filter (), and the amplitudes of the signals IM-I and IM-Q are detected by an amplitude detecting unit (). Based on the detected amplitudes, an element value control unit () controls element values of constituent elements of the complex filter () so as to decrease the amplitudes.
