Frequency multipliers have much in common with frequency mixers, and some of the same nonlinear devices are used for both : transistors operated in gain ) produced by the nonlinear device drops off rapidly at the higher harmonics, so most frequency multipliers just double or triple the frequency, and multiplication by higher factors is accomplished by cascading doubler and tripler stages.
