Bias Tee

A bias tee is a device with three connections that helps set the DC voltage for some electronic parts without affecting other parts. A bias tee is a device that lets two signals share the same line. The low-frequency port is used to set the bias. The high-frequency port allows radio signals to pass through but blocks the bias levels. The combined port connects to the device, which receives both the bias and radio signals.

MCLI’s RF engineers design and build these bias tees in the USA, and they can adjust frequency range, voltage or connectors when a standard model does not fit. We ship from St. Petersburg, Florida to defense, commercial, medical and research customers across the U.S. and worldwide. Engineers choose MCLI for over 40 years of RF manufacturing, in-house testing, and quotes on catalog parts typically within 24 hours.
