Bias Tees are devices used to inject DC Power onto a High Frequency Transmission Line. It is also used on the reverse to remove the same DC Power from the Transmission Line to make that DC Power available remotely at the Point of Load. This is extremely useful in the field where it is not possible to have a Power Supply.
Conceptually, the Bias Tee can be viewed as an ideal Capacitor that allows AC through but blocks the DC bias, and an ideal Inductor that blocks AC but allows DC. Due to the parasitic nature of standard components, the design of Bias Tees becomes significantly more complicated, especially for wide frequency range units.
Bias Tees can also additionally be used to inject Low Frequency RF Signals onto High Frequency Transmission Lines. An example of this is in Satellite Systems where a 10 MHz Clock Reference might be remotely required.
