HO1081-4 Datasheet, PDF (1/2 Pages) Murata Manufacturing Co., Ltd. – 1090.0 MHz SAW Oscillator

• SAW Frequency Stabilization
• Fundamental-mode Oscillation at 1090.0 MHz
• Ideal for ATC/TCAS 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 1090.0 MHz.
The highly-reliable HO1081-4 is designed for use in Mode-S Air Traffic Control Transponders/Traffic Alert and
Collision Avoidance Systems (TCAS).

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_A = +25 ±2 °C, V_CC = 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_O. No instability or damage will occur for any passive load impedance.
6. For any combination of V_CC and T_A 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.
