Abstract
There are provided a sampling mixer, quadrature demodulator, and a wireless device capable of suppressing receiving sensitivity degradation caused by alias components or second-order distortion components. In the sampling mixer (), a sampling switch () and another sampling switch () sample a reception signal based on a local signal with a predetermined frequency. A control signal generator () generates a control signal for controlling a filter operation. An in-phase mixer () and a reverse-phase mixer () perform, based on the control signal, filter processing on the sample signal obtained by the sampling switch (). A delay controller () controls the phase difference between the local signal and the control signal according to a reception-desired frequency.
