What’s a Bias Tee?

A “Bias-Tee”, also known as a “DC Inserter”, is a simple way to feed DC power through coaxial cable to the remote device, such as a pre-amplifier and/or transmit/receive relays via the coaxial cable.

The main task is to inject DC into or extract DC from the coaxial cable, leaving the RF signal undisturbed.

A bias tee is a passive RF circuit consisting of capacitors and inductors. Act as a diplexer by combining DC and RF signals onto a common port RF+DC.
