Original Abstract Submitted

A receiver includes a quadrature mixer to perform frequency conversion to convert a radio-frequency signal into an I signal and a Q signal that have a 90° phase difference from each other and a surface acoustic wave (SAW) device to perform phase conversion on the I signal and the Q signal that are output from the quadrature mixer. In the SAW device, when α° represents a phase rotation amount of the I signal, β° represents a phase rotation amount of the Q signal, and n is an integer, (α+90±n×360−35.1)≤β≤(α+90+n×360+35.1) or (α−90+n×360−35.1)≤β≤(α−90+n×360+35.1).
