Abstract : For the past few years Raytheon has had a program to develop, for potential military applications, SAW oscillators in the 300-600 MHz range which exhibit simultaneously state-of-the-art performance in frequency settability and stability. Though specific applications will not be discussed, the requirements are, in general: (1) The noise floor must be at least - 160 dBc/Hz; (2) Vibration sensitivity should be at least as good as that of AT-cut bulk-wave devices; (3) The oscillator frequency must be set in, and stay in, a window of approximately + or - 10 ppm. In some cases, a warm-up time of less than 3 minutes may be required. Significant progress has been made in meeting these requirements and will be discussed in this paper.
