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 minimum 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.
