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.

One or more of the following United States patents apply: 4,616,197; 4,610,681; and
4,761,616.
Unless noted otherwise, all specifications are listed at TA = +25°C ±2°C, VCC = nominal voltage ±0.01 VDC, and load impedance = 50 Ω with VSWR ≤ 1.5:1.
The design, manufacturing process, and specifications of this device are subject to
change without notice.
Applies to oscillator only and not to sidebands caused by external electrical or
mechanical sources. (Dedicated external voltage regulation with low-frequency filtering for the DC power supply and proper circuit board layout are recommended for
optimum spectral purity.)
For specified maximum operating load VSWR (any angle) at FO. (No instability or
damage will occur for any passive load impedance.)
For any combination of VCC and TA within the specified operating ranges.
Applies for any combination of Note 5 and 6 conditions.
