Amplitude equalized transmission line dispersive delay structure for analog signal processing

An amplitude equalized C-section based all-pass dispersive delay structure (DDS) is proposed and experimentally demonstrated by cascading the DDS with a resistive transmission line network. Using such resistive networks, the frequency dependent dielectric and conductor losses of the transmission lines are equalized. This leads to a flat transmission response of the DDSs which is critical for efficient processing and detection of ultrafast time-domain signals using various analog signal processing (ASP) techniques.
