Synthesizer and reception device using the same

摘要

A synthesizer of the present invention includes a synthesizer section that generates an oscillation signal based on a reference oscillation signal output from a MEMS resonator and inputs the oscillation signal to a frequency converter; and a control section that adjusts a frequency of the oscillation signal output from the synthesizer section. In frequency adjustment by the control section, when a frequency adjustment unit of the synthesizer section is defined as predetermined value F in which quality of an output signal from the frequency converter is a quality limit threshold value, frequency adjustment unit &Dgr;fcont of the synthesizer section is within predetermined value F.
