Abstract
A phase shifter having both digital and analog shifting components is disclosed. The digital-analog phase shifter includes an input/output port configured, in part, for receiving an input radio frequency (RF) signal from an external source and outputting a phase shifted RF signal. A digital shifter performs coarse phase shifts of the input RF signal, while an analog shifter variably shift the phase of the input RF signal relative to the coarse phase shift. This produces a phase shifted RF signal having a total phase range that is output is continuously variable from 0° to 360°.
