Abstract :
A study of the acoustoelectric strip-coupled real-time convolver and memory correlator using Schottky diode as storage element is presented. This study involves utilization of Schottky diode charges which are estimated by using Green´s function in the calculation of the device efficiency and output power. The theoretical predictions of this calculation are compared with the published experimental results, in which the experimental point of the efficiency is verified at different values of the input power. The dependence of the output power on the depletion depth gives good results in comparison with the published data
