PACKAGING
Amplifier Bias Tee enables the injection of DC supply and ALP
communication signals onto the existing coaxial feeder for simple
implementation of the Tower Mounted Amplifier system.
• Compact and lightweight
• Indoor and outdoor versions available
• Outdoor versions IP68 rated
• Simple installation
Bias Tee - RF Function
TM
The Bias Tee incorporates a network for the injection of DC and ALP
communications signals onto the existing RF feeder. The RF path has low
insertion loss, high return loss and excellent passive intermodulation (PIM)
performance. A high voltage, high Q coaxial capacitor isolates the BTS and
antenna ports while maintaining a low loss RF path. The antenna port DC
injection is achieved by a low resistance high impedance RF isolating
network.
BENEFITS/APPLICATIONS
• ·Low cost of installation
• No additional tower feeders
Bias Tee - DC and Control Function
The Bias Tee DC supply connections are fed onto the RF line via the RF
isolating network. The DC connection is protected by a gas discharge tube
(GDT) with secondary protection using a transient protector diode. For ALP
• Replaces existing lightning protectors
with 10 kA capability
