DC Blocks

Pasternack DC blocks are passive coaxial components that prevent (block) the flow of direct current (DC) frequencies to RF signals. DC blocks from Pasternack are available in 50 Ohm and 75 Ohm designs and can be purchased in inner-only, outer-only and inner-outer DC block styles at varying frequency ranges. Many of our RF DC blocks are RoHS and REACH compliant.

Pasternack’s 50 Ohm coaxial DC blocks can be ordered with 2.4mm, 2.92mm, BNC, Type N and SMA DC block connector types and have frequencies ranging from 10 MHz to 50 GHz. Our 75 Ohm coaxial DC blocks are available with Type N, F and BNC DC block connectors and have frequencies ranging from 10 MHz to 4 GHz. DC blocking voltage ratings for the Pasternack 50 Ohm RF microwave DC block product line ranges from 75 Volts to 950 Volts depending on type.
