Abstract
An acousto-electric amplifier having insertion gain is provided. The acousto-electric amplifier comprises resistive material coupled to sensors such as conductive fingers. The conductive fingers are disposed on piezoelectric material. The piezoelectric material may be disposed on or above the piezoelectric material. Transducers may be used to couple a surface acoustic wave to and from the acousto-electric amplifier. The acousto-electric amplifier amplifies the surface acoustic wave in one propagation direction and attenuates a surface wave in the opposite propagation direction.
