The frequency of this oscillator is stabilized by UHF surface-acoustic-wave (SAW) technology, providing ex-
cellent performance in a compact, rugged oscillator operating at the fundamental frequency of 1030.0 MHz.
The highly-reliable HO1080-3 is designed for use in Mode-S Air Traffic Control Transponders and Traffic Alert
and Collision Avoidance Systems (TCAS).
