Abstract:
1. A synthesizer comprising: a synthesizer section for generating an oscillation signal based on a reference oscillation signal output from a reference oscillator including a micro-electro-mechanical system (MEMS) resonator, and inputting the oscillation signal to a frequency converter; and a control section for adjusting a frequency of the oscillation signal output from the synthesizer section by a frequency adjustment value Δfcont, wherein, when a signal quality of an output signal from the frequency converter is better than or equal to a signal quality represented by a quality limit threshold value, the control section adjusts the frequency adjustment value Δfcont to be less than or equal to a predetermined value F associated with the quality limit threshold value, based on a predetermined relationship between the frequency adjustment value Δfcont and the signal quality.
