Broadband DC Blocks

Spectrum Control Inmet inner DC block 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; outer DC block have a capacitor in-series with the outer conductor and the inner/outer types have capacitors in-series with both inner and outer conductor

Insulation material on the outer DC block is a PEEK shell.
