ABSTRACT:
A method and device for frequency conversion is disclosed in which a first signal with a first frequency is converted into a second frequency through mixing with a divided oscillator signal and wherein the frequency of the divided oscillator signal stands in a fractional rational ratio to the frequency of the undivided oscillator signal. The method is characterized in that the oscillator signal is divided such that an average value of the divided oscillator signal over time corresponds to half the separation between the extreme values of the divided oscillator signal.
