A frequency synthesizer for generating an oscillator signal with a desired frequency includes a first phase locked loop and a second phase locked loop, which is connected in a cascaded manner to the first phase locked loop, such that the second phase locked loop receives, as a reference frequency, a frequency generated by the first phase locked loop. The second phase locked loop outputs the desired oscillator signal at the output of a divider provided in the feedback path of the second phase locked loop. A method of supplying a mixing oscillator signal to a mixer is also provided.
