Description
SMA DC Block – DC–6 GHz, 50-200V DC
The CentronRF SMA DC block passes RF signals from DC–6 GHz while stopping DC voltage, rated to 50-200V. Place it in line to protect the input of a spectrum analyser, signal generator or receiver from DC bias, or to remove DC from a line that carries power to an LNA, active antenna or amplifier.
Its compact body and low VSWR keep it transparent to the RF signal. The precision SMA connector suits lab benches, PCB test points, microwave modules, SDRs and compact RF assemblies where space is tight.
Key features
- Blocks DC up to 50-200V
- DC–6 GHz broadband RF pass-through
- Low VSWR ≤1.15, 50 Ω
- SMA male to female connectors
Applications
- Protecting spectrum analyser and signal-generator inputs from DC
- Isolating bias-tee and phantom-powered lines (LNAs, active antennas)
- Breaking ground loops between test instruments
- Cellular, Wi‑Fi and microwave lab measurements

FAQ
Why do I need a DC block?
Many test instruments are damaged by even small DC voltages at their RF input. A DC block lets the RF signal through while keeping DC out.
Does the DC block affect low frequencies?
It is specified for use across DC–6 GHz. Contact us if you need the low-frequency cut-off for your application.
