Overview:

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

In the practical application, some sites are far from the base station. The input power of the repeater is weaker than the normal power level, and the repeater couldn’t reach its full output power for a much larger coverage size. Then the pre-amplifier could be utilized to boost the input signals to reasonable level, so that the repeater can work with full output power for ideal coverage.

As we know, some pico repeaters only get 5~15dBm in UL and in some remote area the uplink mobile signal wouldn’t be strong enough to go back. That’s why the phone calls can’t be initiated even if we can see full bar signals on the mobile phone. However, we can enhance uplink signal up to 20dBm by adding a pre-amplifier before the repeater. And then the uplink signal can reach base station, and we have a good call in this practical application. 

Advantages:

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. Single system, dual system and triple system pre-amplifier could be tailor made by the client.
