SAW Frequency Stabilization
Fundamental-Mode Oscillation at 1090.0 MHz
Ideal for IFF Transponder Applications
1090.0 MHz
SAW
Oscillator
The frequency of this oscillator is stabilized by surface-acoustic-wave (SAW) technology. This results in excellent performance from a compact, rugged, hermetically-sealed oscillator operating at the fundamental frequency of 1090.0 MHz. The highly-reliable HO1081 is designed for use in identify-friend-or-foe (IFF) radar
transponders in military aviation. Military Screening is available as an option. The HO1081 is a high-performance version of the HO1079 oscillator.

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 = +25°C ±2°C, VCC = nominal voltage ±0.01 VDC, and load impedance = 50 Ω 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.
