Abstract
A system for phase shifting that produces an output signal by modifying a phase of an input signal, including a primary phase shifting stage that modifies the input signal phase in increments set by a first tuning resolution; a secondary phase shifting stage that modifies the input signal phase in increments set by a second tuning resolution; and, a tuning circuit that controls the primary phase shifting stage and the secondary phase shifting stage according to control input.
