Surface Acoustic Wave (SAW) Oscillator Investigation.

This final report describes the results of the development, fabrication, evaluation and test performed by TRW Systems. The main purpose of the SAW oscillator program was to investigate the key performance parameters of SAW oscillators and particularly their short, medium and long term stability. SAW oscillators were fabricated to operate at 250 MHz and 500 MHz, and their performance was evaluated and compared against theoretical predictions. As the data presented in the following sections will show, the performance of these oscillators closely approaches or exceeds the currently reported state-of-the-art in nearly every respect. Perhaps even more important, this performance is related to the fabrication processes in such a way that directions for still better performance can be clearly seen.
