Abstract
A low loss, wide band, phase shifter utilizing one or more transformers in presented. In one case, the phase shifter includes a reflective SPDT switch that is coupled to a transformer. In another case, the phase shifter includes a distributed SPDT switch that includes switchable conduction paths having series connected unit elements of a same phase shift. The transformer may be part of an existing circuit and may be reused to provide the functionality of the phase shifter by introducing the reflective or the distributed SPDT switch.
