A monolithic microwave integrated circuit (MMIC) based true time delay shifter circuit for providing differential true time delay is provided. The MMIC includes two or more of circuits which are disposed in the MMIC and configured to provide a differential time delay based on digital control signals. Each circuit includes a reference path and a delay path. The two or more of circuits includes (i) a first set of circuits realized using a self-switched constant R-network which are adapted to provide a first range of time delay, (ii) a second set of circuits realized using a ultra wide band self switched band-pass delay network which are adapted to provide a second range of time delay and (iii) a third set of circuits realized using a ultra wide band compensated delay network which are adapted to provide a third range of time delay.
