SAW VESTIGIAL SIDEBAND FILTERS
GENERAL DESCRIPTION
These SAW (surface acoustic wave) VSB (Vestigial
Sideband Filters) filters address the needs of broadcast
and cable TV applications. These VSB filters (VSFs)
are designed for television signal IF (intermediate
frequency) filtering, with some models providing high
suppression of the audio carrier while other models
pass the audio carrier without attenuation. The
excellent linear phase characteristics and low group
delay ripple of these VSFs yield superior 2T and 20T
pulse performance. These SAW VSFs provide superior
in-band performance while maintaining high rejection of
adjacent channels.
APPLICATIONS
CATV (Cable TV) Headend Modulators/Combiners
Television Transmitters/LPTV
HDTV IF processing
Satellite and terrestrial distribution
Broadcast/CATV systems
Adjacent channel suppression
FEATURES
Exceptionally low amplitude and group delay ripple
Worldwide broadcast standards supported
Available at standard video intermediate frequencies
DIP packaging, including: DIP-G (35 x 20 mm), DIP-B
(39 x 26), and DIP-O (22 x 13 mm)
