【Abstract】 This paper presents the development and experimental results of the real-time air-gap coupled SAW convolvers, and discusses some of the problems associated with such a convolver.The main performance of our device features an external convolution efficiency of -48dBm,a dynamic range larger than 70dB and a convolution output power larger than-15dBm (load 50*).Some signal processing experiments (including chirp signal, 7 bit Barker code, uniform and non-uniform pulse sequencies, and rectangular pulse) using our convolver have been carried out, and the experimental results are in good agreement with the theories.更多还原
