    BIAS-T



The Bias-T is suitable to feed DC voltage into the feeder cable in order to provide operating voltage via the RF feeder cable to the TMA(Tower Mounted Amplifiers) or RCU.
Rugged construction and broad bandwidth (800MHz to 2200MHz) with great Inter Modulation performance and ultra low insertion loss lets you get the most out of your system performance. Bias-T includes a lightning protection circuit to protect the Power Distribution Unit and the Base Station.



The Bias-T provides low RF signal insertion loss from the BTS to the antenna port and vice versa.

The DC voltage is fed from the DC port to the antenna port while providing a high level of
    DC isolation from the DC to the BTS port and from the antenna to the BTS port.

Lightning ensure a high level of reliability and operational safety.
