ATT and ALC function, High system gain>60dB, High system output power>20dBm

The Wide Band booster is a bi-directional amplifier with manual attenuation and ALC function, which used to enhance signals between a mobile and a base station.

It features with customized frequency band, flexible installation, cost-effectiveness and ideal coverage solution, its output power varies from 10dBm to 20dBm.

It is applied to small, medium-size areas such as home, offices, shops, and basements, remote countryside , car, ship and mining well etc.

System Diagram

The RF link (donor) towards the base station is typically fed from an outdoor antenna while the coverage area is fed by an indoor antenna

 

The RF link (donor) towards the base station is typically fed from an outdoor antenna while the coverage area is fed by an indoor antenna or connected to mobile antenna directly.

The signal from the base station is received via directly antenna, then forwarded through a duplex filter, is amplified in a low noise amplifier (LNA), enters the RF filter for wideband selective, and then amplified in the power amplifier.

The output signal passes a duplex filter, before it is fed to mobile or indoor antenna which retransmits the signal to the aim areas.
