Inmet inner DC blocks have a capacitor in-series with
the center conductor which prevents the flow of audio
and direct current (DC) frequencies while offering min-
imum interference to RF signals up to 50GHz. Similarly,
outer DC blocks have a capacitor in-series with the
outer conductor and the inner/outer types have capac-
itors in-series with both inner and outer conductors.
Insulation material on the outer DC blocks is a PEEK
shell. Applications include ground loop elimination,
signal source modulation leakage suppression, sys-
tem signal-to-noise ratio improvement, test setup iso-
lation and other situations where undesired DC or
audio current flows in the system.
