Abstract
Systems and methods according to one or more embodiments are provided for a true time delay function. The true time delay function may be implemented, for example, as a selectable signal delay circuit for broad bandwidth time control of phased array antenna element signals. In one example, a system comprises a selectable signal delay circuit including a plurality of delay lines, an input port, and an output port, wherein the delay lines are disposed between the input port and the output port. A plurality of amplifiers are coupled to corresponding ones of the plurality of delay lines and coupled between the input port and the output port. A plurality of switches are configured to selectively couple the plurality of delay lines and corresponding amplifiers to provide a selectable delay and amplification between the input port and the output port. Additional systems and methods are also provided.
