摘要

The present invention is applied to a frequency converter used for a receiver. The frequency converter according to the present invention includes an LO signal generator (11) that generates an LO signal and outputs the LO signal; and a mixer (10) that multiplies a received signal that has been band-limited to a usable bandwidth of said receiver by the LO signal so as to convert the frequency of the received signal and outputs the resultant signal. Said LO signal generator is capable of varying a phase resolution.
