SAW Frequency Stabilization  
Fundamental-Mode Oscillation at 915.0 MHz  
0.8” x 0.5” x 0.25” Metal Dip Case  
915.0 MHz  
SAW  
Oscillator  
This 915.0 MHz surface-acoustic-wave (SAW) oscillator is designed for Industrial, Scientific, and Medical  
(ISM) applications and as the local oscillator in FCC Part 15.247 radios. Fundamental oscillation at 915.0 MHz  
eliminates all internally generated spurious outputs except integral harmonics of 915.0 MHz. The compact  
size of the rugged, metal, hermetically-sealed case makes this oscillator suitable for a variety of applications.
