This is a receiver comprising the first local oscillator, the first mixer, the first frequency switching means, the second local oscillator, the second mixer and the second frequency switching means. If N and M are natural numbers, the frequency of the first local oscillation signal generated by the first local oscillator is switched in such a way that a frequency of Nxf1 +/- Mxf2 is greater by a prescribed value or more than the frequency of the incoming signal, that of the first IF signal and the second IF signal. The frequency of the second local oscillation signal is switched in such a way that the frequency of the second IF signal corresponds to the frequency of the first IF signal. <IMAGE>
