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. Like EME2-50, EME2-70, or Preamplifiers.

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, combining DC and RF signals onto a common port (RF+DC).
