ESCRIPTION
The family of SAW (surface acoustic wave) Delay Lines
addresses the needs of fiber-optic networks and
wireless communication systems. Some models are
used for SONET/SDH oscillator and CDR (clock and
data recovery) applications. Other models provide
optimal signal processing for CDMA applications. All of
the SONET delay lines are fabricated on quartz
substrate material for optimum phase and frequency
stability over temperature. These delay lines have low
insertion loss and good stopband rejection.
