Description signal repeater

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. A typical phenomenon 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. Huaptec's pre-amplifiers are available in single, dual and triple mobile systems, i.e., not only we have pre-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 pre-amplifiers are still compact size, elegantly looking with low power consumption.
