Abstract
A calibration signal is generated from a modulating signal having a first frequency and a carrier signal having a second frequency. A single-sideband mixer modulates the modulating signal on the carrier signal. At least two frequency dividers by two connected in cascade receive the modulating signal modulated on the carrier signal and generate an output of the calibration signal.
