SAW Frequency Stabilization
Fundamental-Mode Oscillation at 310.0 MHz
0.8” x 0.5” x 0.25” Metal Dip Case
310.0 MHz
SAW
Oscillator
This general-purpose oscillator is stabilized by surface-acoustic-wave (SAW) technology. Fundamental oscil-
lation at 310.0 MHz eliminates all internally generated spurious outputs except integral harmonics of 310.0
MHz. The compact size of the rugged, metal, hermetically-sealed case makes this oscillator suitable for a va-
riety of applications.
