Abstract
A sinusoidal signal frequency multiplier, including a means for stabilizing the static input-ouput phase relationship. The static phase stabilizer compares the phase relationship between the frequency-multiplied output and the input signals, producing a signal which appropriately controls a phase shifter. This phase shifter operates on the input signal, the result serving as input to the frequency multiplier.
