The purpose of this study is to suggest new approaches to the use of surface acoustic wave technology in communications systems. The problem was approached by considering the basic physics of the waves and their interactions with themselves, the electrons, and with photons. Three devices that used SAW components were analyzed on the basis of the basic physics, and their performance was compared with non-SAW devices, where possible. The three devices were a SAW convolver with bidirectional amplification, an AD converter using a SAW-generated reference waveform, and a phase-lock loop using acoustic waves for the mixing and filtering functions. Based on the analysis of those devices, new approaches are suggested. The devices suggested were a mixer that delays one input relative to a second input a variable Q, high Q bandpass filter and a filter that selects a signal based on an impurity pattern in a semiconductor.
