Abstract

This short paper is on the development of real-time air-gap coupled SAW convolvers. The convolver is "degenerate" Its center frequency is 60 MHz, the interaction length 8is, untuned convolution efficiency F_Te=-66dBm, tuned F_Te>-57dBm, and the figure of M=6.1×10^-3V·m/W.
We have made two experiments using the modulated square pulses and the linear chirp signals by our convolvers. These experimential results were satisfactory.
