Abstract

See full text

An all-pass wideband phase shifter is introduced. Series connections in parallel between two 3 dB hybrid couplers include combining two 90-degree phase shifters and two attenuators to form a novel phase shifter framework. Under specific controls of continuous 90-degree phase shifters and attenuators in four quadrants, 360-degree all-pass phase shifting is effected by phase shifting and vector composition.
