This general-purpose oscillator is stabilized by surface-acoustic-wave (SAW) technology. Fundamental oscil-

lation at 750.0 MHz eliminates all internally generated spurious outputs except integral harmonics of 750.0

MHz. The compact size of the rugged, metal, hermetically-sealed case makes this oscillator suitable for a va-

riety of applications.
