PIEZO FILTERS
CERAMIC FILTERS LOW LOSS, WIDE OR
NARROW BAND, MINIATURE
SFE MA/MTE/MVE/MFP 10.7MHz
The following filters were developed to offer both narrower
and wider bandwidth characteristics for use in products such
as DBS receivers. These filters also retain the same reliability
that is available with our standard filters. The various
bandwidths allow these filters to be utilized in a multitude
of new communication applications.
