Fundamental-Mode Oscillation at 400.0 MHz
A Rugged, Compact General-Purpose Oscillator
Complies with Directive 2002/95/EC (RoHS)
400.0 MHz
SAW
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 400.0
MHz. The high-reliability of the HO4002-1 makes it suitable for general purpose use in a wide variety of
applications.
