Product Description

Product name : Pre-Amplifier

Item : PA20


Details :

Work Frequency: 

CDMA450, LTE700 (A/B/C/D), IDEN800, CDMA800, GSM900 & EGSM, DCS1800, PCS1900, CDMA2000, WCDMA2100, AWS2100, LTE2600 and so on. 


Overview: 

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.

Lenolink 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.

Though it supports up to triple band , the pre-amplifiers are still compact size, elegantly looking with low power consumption. 


Features:

1. Elegant and compact design.

2. Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

3. Light weight, small volume, simple and convenient installation design.
