HO1091 fiche technique
• SAW Frequency Stabilized
• Fundamental-mode Oscillation at 1090 MHz
• Ideal for ATC Transponder Applications
• Complies with Directive 2002/95/EC (RoHS)
2>
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 1090 MHz. The
highly-reliable HO1091 is designed for use in Air Traffic Control Transponders.

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. One or more of the following United States patents apply: 4,760,352; 5,787,117; and
7,260,375.
2. Unless noted otherwise, all specifications are listed at TA = +25°C ±2°C, VCC = nom-
inal voltage ±0.01 VDC, and load impedance = 50 with VSWR 1.5:1.
3. The design, manufacturing process, and specifications of this device are subject to
change without notice.
4. Applies to oscillator only and not to sidebands caused by external electrical or
mechanical sources. (Dedicated external voltage regulation with low-frequency filter-
ing for the DC power supply and proper circuit board layout are recommended for
optimum spectral purity.)
5. For specified maximum operating load VSWR,any angle, at fO. No instability or dam-
age will occur for any passive load impedance.
6. For any combination of VCC and TA within the specified operating ranges.
7. Applies for any combination of Note 5 and 6 conditions.
