RF Bias Tee - 10MHz to 6GHz, SMA

Feed DC power into an RF cable without running a separate power lead along the same route. This SMA bias tee combines RF and DC connections for compatible powered RF equipment, including LNA and radio projects.

✅ Simplify the cable route - Combine DC power and RF on a shared coaxial feed.

✅ Work across a broad frequency range - The specified 10 MHz to 6 GHz range accommodates varied RF projects.

✅ Connect with SMA cabling - SMA interfaces suit equipment already using this common RF connector.

A More Practical Power Feed for RF Projects

An inline amplifier or another powered RF component needs both a signal connection and a power supply. A bias tee lets the coaxial feed carry DC as part of that arrangement, reducing the need for a separate lead along the cable run.

At the workbench, the module gives you a compact way to assemble a powered signal path. Match the connected equipment's voltage, current and connector requirements before applying power; the bias tee itself does not set the supply voltage.
