SAW Frequency Stabilization
Fundamental-Mode Oscillation at 1030.0 MHz
Ideal for Air Traffic Control Transponder Applications
1030.0 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, oscillator operating at the fundamental frequency of 1030.0
MHz. The highly-reliable HO1078 is designed for use in air traffic control (ATC) radar transponders in commercial aviation. It is a commercial version of the HO1080 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.
