Product Description
The TGB2010 Bessel Filter has low inband
return loss, low group delay variation, and a
smaller package footprint than competing
filters. Insertion loss and group delay for each
filter matches an ideal 3rd order Bessel filter
and is matched to 50 Ohms eliminating the
need for additional components for multiple
reflection management.
A range of 5 to 9 GHz cutoff frequencies in
1GHz steps are available. The TGB2010
series package size is 2mm x 2mm allowing
integration on tightly packed circuit boards.
