Fundamental-Mode Oscillation at 310.0 MHz
0.8" x 0.5" x 0.25" Metal Dip Case
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.

The design, manufacturing process, and specifications of this device are subject to
change without notice.
4.
Applies to oscillator only and not to sidebands caused by external electrical or
mechanical sources. (Dedicated external voltage regulation with low-frequency filter-
ing for the DC power supply and proper circuit board layout are recommended for
optimum spectral purity.)
