TLDR
In this paper, two approaches to frequency division multiplexing using SAW devices are described, one using a 9-channel filter array, where the signal combining and splitting is performed using wide-band power splitters.Abstract:
Two approaches to frequency division multiplexing using SAW devices are described. The first one uses a 9-channel filter array, where the signal combining and splitting is performed using wide-band power splitters. Two of these filter arrays were used in a data link, with data rates up to 7.5 Mbit/s for a total data rate of 67.5 Mbit/s. The second approach uses offset multistrip couplers to channel a wide-band signal into various narrow-band outputs according to frequency. Consequently, this approach exhibits lower insertion loss and is especially suitable for a large number of channels. An 8-channel MSC multiplexer has been constructed with less than 10-dB insertion loss.read more

Acoustic surface wave convolver with bidirectional amplification
TL;DR: In this article, the convolution of two input signals introduced at opposite ends of an acoustic surface wave propagation medium provides amplification of the two oppositely propagating signals and their integration in an intermediate semiconductor film cooperating with a contiguously overlying electrode pattern serving both as the signal output transducer and coupling unidirectional electrical bias fields for amplifying the convolved output.
