DC Blocks are coaxial components that prevent the flow of audio and direct current (DC) frequencies while offering minimum interference to RF signals.
There are three kind of DC blocks.
Inner only DC Blocks: the models have a capacitor in series with the center conductor.
outer only DC Blocks: the models have a capacitor in series with the outer conductor.
inner/outer DC Blocks: the Models have capacitors in series with both the inner and outer conductors.
The insulation material on the outer models is non-conductive. Applications include ground loop elimination, signal source modulation leakage suppression, system signal-to-noise ratio improvement, test setup isolation and other situations where undesired DC or audio current flows in the system.
Applications
Include the blocking of current surges in subway and train tunnels.
BECEN RF have SMA-JK DC Blocks, N-JK DC Blocks and high voltage 3000V N-JK DC Blocks. The impendence of our DC Blocks are 50Ohm.
