Outer DC Blocks

Pasternack outer DC blocks are passive coaxial components that prevent (block) the flow of direct current (DC) frequencies to RF signals. Outer DC blocks have a capacitor that is in-series with the outer conductor. Outer DC blocks from Pasternack are available in 50 Ohm and 75 Ohm designs and can be purchased with varying frequency ranges. Many of our RF outer DC blocks are RoHS and REACH compliant.

These 50 Ohm outer DC blocks can be ordered with 2.4mm, 2.92mm, BNC, Type N and SMA connector types and have frequencies ranging from 10 MHz to 50 GHz. Our 75 Ohm outer DC blocks are available with Type N, F and BNC connectors only and have frequencies ranging from 10 MHz to 4 GHz. Voltage ratings for the Pasternack RF and microwave 50 Ohm outer DC blocks range from 75 Volts to 200 Volts depending on style. Our 75 Ohm RF outer DC blocks are available with voltage ratings of 200 Volts.
