Abstract
A true time delay ('TTD') system with wideband passive amplitude compensation is provided. The TTD system includes an input switch, an output switch, a reference delay line disposed between the input switch and the output switch, and time delay lines disposed between the input switch and the output switch. Each time delay line ('TDL') has a different line length, and includes a center conductor between two corresponding ground planes. Each center conductor has a width and is separated from the two corresponding ground planes by a gap space. For each TDL, the width of the center conductor is configured such that a loss of the TDL is substantially the same as a loss of every other TDL over a range of operating frequencies. For each TDL, the gap space is configured such that an impedance of the TDL is substantially the same as an impedance of every other TDL.
