Description
• M/A-COM Technology Solutions' MAFL-009272-
CD0AC0 is a surface mount diplex filter unit designed for
MoCA applications.
This filter includes the addition of an off chip circuit exter-
nal to the diplex filter. This circuit improves rejection be-
tween 2GHz - 3GHz.
Recommended rejection circuit configuration, Recom-
mended component values and typical spec table are
given below.
