DC Block
Designed to prevent the flow of direct current (DC) while allowing RF signals to pass through, DC blocks are essential passive components in protecting sensitive equipment and maintaining signal integrity across RF systems. They are commonly used to isolate DC voltages, protect measurement instruments, and eliminate unwanted current paths.

FAQ about DC block
What is a DC block and what does it do?
A DC block is a passive RF component that prevents the flow of direct current (DC) while allowing radio frequency (RF) signals to pass through. It’s used to isolate DC voltages in a system and protect sensitive equipment.
What are the types of DC blocks?
There are three main types:
-
Inner-only: blocks DC on the center conductor only.
-
Outer-only: blocks DC on the outer conductor (shield).
-
Inner/Outer: blocks DC on both conductors.
Each is used based on the application’s grounding and isolation needs.
Where are DC blocks commonly used?
DC blocks are widely used in RF test setups, telecommunications equipment, satellite systems, and any application requiring DC isolation to protect instruments or prevent ground loops.
What frequencies do DC blocks typically support?
High-quality DC blocks, such as those from MCV, support a broad frequency range — from low MHz to several GHz — with low insertion loss and excellent return loss.
How do I choose the right DC block for my application?
Selecting the right DC block depends on factors like frequency range, connector type, power handling, and whether you need inner, outer, or both conductor isolation. MCV offers a variety of options tailored to specific system needs.
