The pre-amplifier provides an affordable solution to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. And its easy installation and maintenance can help carrier get fast return.
The pre-amplifier is working as a relay between the BTS and repeater. It picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the repeater. And the repeater signal is also amplified and retransmitted to the BTS via the opposite direction.
Linear power amplification to effectively suppress inter-modulation and spurious emission
Smart Automatic Level Control (ALC) ensures output level stable and adjustable continuously
Auto Isolation check between service and donor antennas
Smart Mode to auto-adjust gain according to the isolation and signal level received by donor site
Simple installation with external AC/DC adapter
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
