SAW Frequency Stabilized

Fundamental-mode Oscillation at 1090.0 MHz

Designed for ATC/TCAS Transponder Applications

Complies with Directive 2002/95/EC (RoHS)

1090.0 MHz

SAW

The frequency of this oscillator is stabilized by UHF surface-acoustic-wave (SAW) tech-

nology, providing excellent performance in a compact, rugged oscillator operating at the

fundamental frequency of 1090.0 MHz. The highly-reliable HX1081 is designed for use

in Mode-S Air Traffic Control Transponders/Traffic Alert and Collision Avoidance Sys-

tems (TCAS).

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 T = +25 ±2 °C, V = nominal voltage ±0.01 VDC, and load impedance = 50 Ω 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 filtering 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 F . No instability or damage will occur for any passive load impedance.

6. For any combination of V and T within the specified operating ranges.

7. Applies for any combination of Note 5 and 6 conditions.

8. Start-up time is defined as the time from when 90% of Vcc is applied to the Enable Pin until the RF output reaches 90% of its steady-state

output level.
