ESCRIPTION
This family of SAW (surface acoustic wave) filters
provides exceptionally low amplitude and phase ripple
to meet the demanding needs of broadband access
and cable router applications. The filters are available in
standard bandwidths for international cable standards
(typically from 6MHz to 8MHz) and custom bandwidths
up to 70MHz. Available center frequencies include
standard and custom center frequencies up to 480MHz.
SMT and DIP packages are available.
