An additional benefit of the hybrid ring is to alternately provide equally-split but 180 degree phase-shifted output signals.
9/16/2002 The 180 Degree Hybrid.doc 2/3 Hence, this coupler is likewise a 3dB coupler—the power into a given port (with all other ports matched) is equally divided between two of the three output ports. Note the relative phase between the outputs, however, is dependent on which port is the input. An active hybrid combiner and circulator has also been patented as an active three-port coupler . A 180° broadband tunable directional coupler with two amplifier stages, two close-to-90° phase shift stages, and varactors is given in [20, 21]. The bandwidth of this active coupler is set by the phase tolerance for the desired directivity.…
