BLK Coaxial DC Blocks

Mini-Circuits BLK Coaxial DC Blocks with a wide frequency range and low insertion loss operate at a minimum -35°C/-55°C case temperature. These DC blocks provide good matching for 50Ω/75Ω systems and minimize signal reflections across a wide frequency range. The BLK coaxial DC blocks feature rugged unibody construction and are RoHS compliant. These DC blocks are used in communication systems, defense systems, and test and measurement instrumentation.
