Our RF Smart Bias Tees combine the performance of a Standard Bias Tee with the function of an additional modem based on AISG standards. 

The RF Smart Bias Tee provides DC power as well as remote control signals via an RF coaxial feeder cable to a Tower Mounted Amplifier (TMA) or Remote Control Unit (RCU or RET) of an antenna. A low RF signal Insertion Loss (IL) from port 1 to port 2 and vice versa is a key feature of our Smart Bias Tee. It also includes a protective device against static discharge and lightning ensure a high level of reliability and operational safety.

We offer 4 different models where DC voltage ranges +10 … +30 V DC for use near the BTS in order to feed-in DC voltage and RCU or RET control signals into a feeder cable and for use near the antenna in order to control an RCU (only required if no TMA is used).
