A frequency synthesizer should not be characterized as a frequency multiplier. Classic multipliers run the input through a nonlinear circuit and harvest a harmonic. They don't have an independent oscillator. That a frequency synthesizer happens to generate only multiples of a reference frequency does

except that it is usable at microwave frequencies, and its resonant frequency is electrically tunable over a wide range by varying the magnetic field on the crystal. In a YIG multiplier, an input frequency is applied to a step-recovery diode mixer, generating harmonics. The YIG filter allows one
410:
I agree with both the above. Only a short mention that PLLs are also used to multiply frequencies is necessary. BTW in the first sentence the term "harmonic" should be replaced by "multiple" to make the article more understandable to elementary readers.

harmonic to pass to the output and filters out the rest. Which harmonic is output can be changed by tuning the YIG filter, so the circuit can function as a frequency multiplier where the multiplication factor, N, can be varied. --

This article explains how modern frequency multipliers work, but what about pre-vacuum tube circuits? For example, the arc-converter transmitter article mentions frequency multipliers and links here.--

Perhaps a passing reference should say that PLL's have replaced many classic frequency multipliers and provide a link to their article.
