Abstract :
A dispersive delay line with two nonperiodic dispersive transducers was described. This construction can be used to design wideband DDL with relatively low insertion loss. A DDL with centre frequency 70 MHz and bandwidth 40 MHz was designed and manufactured. The slanted transducer technique used to eliminate interelectrode reflections and Fresnel ripple was also presented
