LPA2100-160-SW01 SPECIFICATION
1. System advantages
Bravo Tech Inc 's newly introduced Multi-Carrier High Power Outdoor Booster platform provides high
er downlink EIRP and improved uplink sensitivity at the same time to extend the coverage of existing cellu
lar networks. This multi-carrier based product platform can also work with customized BTS to extend capa
city of original BTS with a low system total cost. This product platform features:
• Support multi-carrier CDMA signals, with mixed mode operation
• Output maximum power 160W, support carriers number up to 4.
• Very High System Efficiency
• Extensive product monitoring and control (local and remote)
• Centralized system control/display/alarms
• Great system reliability supported by architecture built-in redundancy
• Powered by 30VDCavailable
• Extensive protection for lightning, voltage surge, and any high failure rate assemblies
• Compact system size and light weight

5.5 Warning
1. Check the power supply voltage is between 24V and 32V or not before electrify, better
to setup in 30V. Power of power supply shall bigger than 1400W.
2. Ensure the power supply polarity is right, port A1、A2 are anode, and port A3、A4 are
cathode.
3. Ensure the output line is connected and input power is not over load before connect
the RF input line.
4. Use the type N connector as output connector, for the high output power, suggest to
using the φ3 upwards RF cable to connect. At the same time, output matching deman
d all right, SWR more than 1.5 is better, but less than 3.0.
5. Product operating should be cooled by air flow, air flow more than 150cfm.
6. Product operating room temperature can’t above 50o ,also can’t below -20o。
