Abstract : The surface acoustic wave device which generates two coherent signals from a single input. The inventive device has three interdigital transducers (IDT) spaced upon a single piezoelectric substrate. The central IDT has three sets of interdigital fingers. A power splitter and an amplifier are connected between the central IDT and one of the other IDT's to form a recirculation loop. An input signal burst applied to the central IDT produces two coherent outputs at the remaining IDT and the power splitter. (RH).
