Abstract :
A precision, low-noise, highly sensitive, synchronous RF detector is described that permits simultaneous phase and level nulling in complex insertion ratio measuring systems. This insertion ratio is a measure of both the phase shift and magnitude change produced by a network when inserted in a transmission path.
