The requirements presented in the introduction of this paper represent a large number of typical military and commercial applications. When SAW oscillators which meet these requirements are available in production quantities, there will be a significant increase in the number of applications where they are used. Our program to develop SAW oscillators has made significant progress in meeting these goals and results are very encouraging. However, several tasks still need to be performed. A very important one is the demonstration of low aging in devices operating in a non-laboratory environment. Also, further improvement in device settability would be very useful. A reduction in frequency shift during bake-out and sealing would greatly increase the accuracy of frequency trimming and the use of reactive ion etching for trimming resonators may very well be more desirable than using gold pads. Finally, there were some packaging differences between the devices used for the aging test and those which were used to demonstrate vibration sensitivity and fast warm-up. These differences must be removed before it can ?e conclusively demonstrated that all of the above requirements can be obtained simultaneously with SAW oscillators.
