HO1079
* * * SAW Frequency Stabilization Fundamental-Mode Oscillation at 1090.0 MHz Ideal for Air Traffic Control Applications
The frequency of this oscillator is stabilized by surface-acoustic-wave (SAW) technology. This results in excellent performance from a compact, rugged, oscillator operating at the fundamental frequency of 1090.0 MHz. The highly-reliable HO1079 is designed for use in air traffic control (ATC) radar transponders in commercial aviation. It is a commercial version of the HO1081 oscillator.

BLOCK DIAGRAM CAUTION: Electrostatic Sensitive Device. Observe precautions for handling, COCOM CAUTION: Approval by the U.S. Department of Commerce is required prior to export of this device. Notes:
1. 2. 3. 4. 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 = +25C 2C, VCC = nominal voltage 0.01 VDC, and load impedance = 50 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.
