Electronically Programmable PSK SAW Devices.

Abstract

This report describes the work conducted by United Technologies Research Center during the period from 7 July 1975 through 6 October 1975, on a research and development program entitled, 'Electronically Programmable PSK SAW Devices.' Research under this program is directed toward the development of a state-of-the-art Surface Acoustic Wave (SAW) module for use in electronically programmable, long code PSK signal correlation and encoding. The program is based on the UTRC PSK Diode-Correlator, a unique SAW device that utilizes non linear mixing phenomena in a hybrid semi conductor delay line configuration. When fully developed in 64 and 128 tap modular form, the PSK Diode-Correlator module will provide advantages in maximum chip rate, minimum tap dissipation, and electronic flexibility. Work during this quarter has been directed toward the fabrication and testing of a programmable 64 tap PSK Diode-Correlator. This prototype design has incorporated several significant modifying improvements to previous diode correlator configurations in order to minimize device insertion loss and spurious signal level. The following report details the design improvements, operational characteristics and experimental encoding and correlation performance of the 64 tap prototype PSK module. (Author)
