RF frequency multiplier is an electronic circuit that generates an output signal whose output frequency is a harmonic (multiple) of its input frequency. Frequency multipliers consist of a nonlinear circuit that distorts the input signal and consequently generates harmonics of the input signal.

contact us· A frequency multiplier will increase the phase noise of the source because it is a phase/frequency multiplier, and it will multiply the phase deviations as well as the input signal''s frequency. Similarly, a frequency divider, often comprised of semiconductor prescalers, will contribute additive phase noise to its lowerfrequency, divided outputs.
