A hybrid circuit surface acoustic wave delay line based oscillator was developed in response to an airborne system application. The 160.7 MHz oscillator's electronic frequency tuning range is extremely wide, approximately plus/minus 275 kHz (plus/minus 1700 ppm). In addition, analog electronic temperature compensation to better than plus/minus 30 ppm at the center of the oscillator's voltage tuning range was incorporated into the design. A phase noise level of better than -80 dBc/Hz at 100 Hz carrier offset frequency was demonstrated on several prototypes. Finally, a vibration sensitivity less than 1x10-9 /g per axis was achieved in order that the oscillator would operate satisfactorily in the comparatively high vibration airborne environment without significantly degraded phase noise performance.
