Main types of multipliers
If a signal of frequency F is applied to the input of a frequency multiplier, the output signal will be at frequency nF, where n is the order of multiplication. The first frequency multipliers ( , ch. 7) were realized with varactors in parametric amplifier-type circuits. They had the advantage of low noise. Another possibility is to use diodes with a very steep
