SINGLE-PHASE CONVERTER OF SURFACE ACOUSTIC WAVES

摘要

The invention relates to acoustoelectronics and can be used, e.g., in the information processing monolithic devices formed on a substrate of gallium arsenide. The aim of the invention is to reduce the losses. Alternating zlektrod converter includes a comb having an electrode width L / 2 disposed on pezopoluprovodni- kovoy substrate with a nonuniform thickness profile of doping, and a system of elastic inhomogeneities in the form of projections of width A / 4, the distance between the centers of the electrodes and L equals n inhomogeneities I ± 3/8 (n = 0,1,2 ...). 1 -yl ^.
