The present invention provides a system for providing a bi-directional vector modulator in which the signal can travel in either direction while the phase shift remains constant. In addition to the functionality of being a phase shifter, the disclosed invention acts as a vector modulator by having the ability to continuously control both the amplitude and phase of a signal.
