Detailed Description
 


1.ETSI & 3GPP 3GPP2 standards
2.DL power level of 20dBm for larger coverages
3.DL AGC 10dB range to ensure high linearity

Description

Line amplifier is utilized when the output power of the repeater or BTS is not enough to cover the targeted areas, each line amplifier will provide an additional 20dBm power level, enough to cover between 1000~3000 square meters, and if the capacity of donor signals are sufficient, more than 20 line amplifiers can be deployed, thus a quite large coverage can be achieved.  

 

Line amplifier can also be used when the cable runs too long and the signals suffer a big loss, then a line amplifier will be fit into the main cable line to boost the signals again.

 

Huaptec's line amplifiers are available in single, dual and triple mobile systems, i.e. not only we have line amplifier able to amplify one GSM900 system, but also a triple system one to support GSM900, DCS and WCDMA at the same time.

 

It supports all current technologies of GSM850, GSM900, DCS, PCS; CDMA450, CDMA800, CDMA1900, CDMA2000, WCDMA2100 and AWS Though it supports up to triple systems, the line amplifiers are still compact size, elegantly looking with low power consumption.
