ABSTRACT:
A frequency multiplier is shown to include either a frequency doubler or a frequency tripler coupled to an amplifier with a temperature compensation circuit and a feed forward gain control loop. With such an arrangement, a frequency multiplier is provided wherein variations of an output signal of the frequency multiplier are minimized due to changing characteristics of the frequency multiplier caused by ambient temperature variation or from a varying input signal level.
