Abstract
A device article and method for an open loop calibrated phase wrapping phase modulator. A tapped delay line may provide a coarse resolution for one or more phases of a signal. A phase multiplexer may receive one or more coarse phases from the tapped delay line and select a coarse phase to send to the digitally controlled delay line. A digitally controlled delay line may provide a fine resolution to the coarse phase from the phase multiplexer.
