The BLK-18-S+ is a coaxial DC Block made by Mini-Circuits. DC blocks are used in RF/microwave signal paths to block (i.e. prevent) DC or low-frequency components (or unwanted bias) from passing, while allowing RF signals through. This one is designed for SMA connectors (female/male), 50 Ω systems, and operates over a broad frequency range.
Some extra details:
-
It is RoHS-compliant.
-
Suitable for use in test & measurement, communication systems, and related signal chains.
-
Rugged unibody construction.
