Product Description

CDMA450 Pre-amplifier for  20dBm moblie repeater good helper of repeaters

GW-20PA(CDMA450)

1. Wide band pre-amplifier to support all signals
2. ETSI & 3GPP 3GPP2 standards
3. Enough UL power level of 20dBm to reach BTS
4. UL AGC 10dB range to ensure high linearity
5. UL IM3 meets with ETSI 3GPP 3GPP2 standards
6. Alarm LED's for error detection
7. Universal power range of 90V~265V
8. Elegant designlight weight low power consumption

Description:

Pre-amplifier is utilized when the input power of the repeater is weaker than the suitable power level, pre-amplifier will boost the input signals to a certain reasonable level, so that the repeater can reach its full output power for a much larger coverage size.
Pre-amplifier has also been largely deployed to assist the Pico repeater operation in rural areas. As it is known, the Pico repeater only gets 5~15dBm output power in UL, so when the repeater site is too far away from the BTS tower, the mobile phone signals would not be strong enough to go back. Typical phenomena is that people can see full bar signals on the mobile phone, but the phone calls can't be initiated. So a pre-amplifier with 20dBm output power in UL would increase the UL power level of the repeater so that the signals can reach BTS tower.
pre-amplifiers are available in single, dual and triple mobile band , i.e., not only we have pre-amplifier able to amplify one GSM900 band , but also a triple band  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 band , the pre-amplifiers are still compact size, elegantly looking with low power consumption.
