An inline DC block that breaks the centre conductor with a series capacitor, so RF from 10 MHz to 18 GHz passes while DC up to 50 V is blocked. Use it to protect an instrument input from a DC bias on the line.

In the box
- 1 × SMA DC block
Questions
Does it block DC on the shield too?
No. It blocks DC on the inner conductor only; the outer conductor stays connected.
Will it pass my 10 MHz reference?
Yes. The stated range starts at 10 MHz.
How much DC can it stand?
Up to 50 V DC, with RF input up to 2 W.
