SAW Oscillator Investigations. Crystal Rotation, Saw Oscillator Aging.

Abstract

This final report describes the results of two surface acoustic wave oscillator studies. The first study demonstrated a new technique for varying the frequency of operation of SAW delay lines. The second study continued the ongoing aging test of four 250 MHz oscillators which was started in July 1975, and measured the aging rate of a new pair of oscillators fabricated using SAW delay lines with chrome/gold metallization. Future high performance communication systems will require frequency sources at UHF and microwave frequencies. SAW oscillators offer several advantages over bulk crystal oscillator multiplier chain type sources. The higher fundamental frequency capability of the SAW device eliminates the need for a multiplier chain, thus reducing size, weight, and power while providing superior phase noise characterisitics.
