LPA1900-120-SC01 SPECIFICATION

1. System advantages

Bravo Tech Inc’s newly introduced 1930~1990MHz only for CDMA Carrier High

Power Outdoor Amplifier platform provides higher downlinks EIRP to extend the

coverage of existing cellular networks. The antenna used for this transmitter must

be fixed-mounted on outdoor permanent structures. This multi-carrier based

product

platform can also work with customized BTS to extend capacity of original BTS

with a low system total cost.

This product platform features:

• Support multi-carrier CDMA signals.

• Output maximum power 120W, 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
