Abstract :
A 375 MHz SAW resonator controlled oscillator is developed for application in the transit satellite marine navigation system. The SAW oscillator, in a two-cubic-inch hybrid package, contains a heater, voltage regulator and divider and is a direct replacement for a bulk wave oscillator and its multiplier chain. Short term stability of 2 x 10E -10 and aging of 3 x 10E -8/day were achieved at 75/spl deg/C. Comparison tests showed that the navigation system accuracy with the SAW oscillator was equivalent to a bulk oscialltor.
