Abstract
New SAW-convolver structures with high-performance characteristics were proposed. Strong piezoelectric substrates which provide high-conversion efficiencies can be used. Fundamental experiments showed their complete temperature-compensation effects unrelated to TCDs of the substrates and applicabilities of high-bit-rate CDMA transmissions with more than several Mbps
