Abstract
A phase detector which determines the phase based upon the output signals from a power coupler. The power coupler outputs a first signal and a second signal. The first and second signals are input to a magnitude detector which determines the magnitude of the relative phase between the first and second signals. The first and second signals are also input to a sign discriminator which determines the sign of the phase between the first and second signals.
