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 current from the coaxial cable, leaving the RF signal undisturbed. A bias tee is a passive RF circuit...
