Product Description

Specifications of BIAS TEE

Main Features

The Bias Tee is suitable to feed DC voltage into the feeder cable of a receiving and/or transmitting antenna system in order to provide the operating voltage for a mast head amplifier.
• The Bias Tee 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.                                                        
•The measures taken to protect against static discharge and lightning ensure a high level of reliability and operational safety.
