Abstract
A true time delay (TTD) module includes a substrate and a transmission line formed on the substrate. The transmission line includes time delay lines that define signal paths of varying lengths between a signal input and a signal output of the TTD module. A plurality of switching elements are positioned along the transmission line and are selectively controllable to define a signal transmission path between the signal input and the signal output. The switching elements include an input switching element positioned at a first end of each of the plurality of time delay lines, an output switching element positioned at a second end of each of the plurality of time delay lines, and at least one intermediate switching element positioned between the input switching element and the output switching element of at least one of the plurality of time delay lines.
