20dBm GSM DCS WCDMA Triple Band Repeater

Features

1 Provide quick coverage solution for small signal weak & block zones.reduce drop/off calls.

2 Compact size, low consuption, easy installation, great cover.

3 Cover about 200~3000 m² without block or obstruct.

4 Reduce cellphone transimt power and radiation, extend cellphone battery life.

5 High linear design, low interference to BTS.

6 Manual Gain Control function.

7 Triband in one repeater, effectively reduce the project cost.


Block diagram and work principle:

The triple band repeater is a bi-directional repeater that consists of three mobile systems, the three systems are combined together by a combiner, and each system gets their independent uplink and downlink power amplifying system, and each link consists of duplexer, LNA, Filter and PA. The triple band repeater downlink receives, amplifiers and retransmits the signals over the air from BTS to the coverage area; at the same time,  the uplink receives, amplifies and retransmits the signals of MS back to BRS, therefore a successful communication is accomplished.
