RF Repeater is designed to enhance cellular network coverage and fill blind spots. Main operation of the repeater
is to receive low-power signal from Base Station (BS) via radio frequency (RF) transmission by its donor antenna,
process, amplify and forward the signal to Mobile Station (MS) in target coverage area by its service antenna.
1.Aluminum alloy enclosure for excellent heat dissipation,waterproof design for all-weather installation;
2.Metal cavity filter technology inside, which gives wider receiving and sending separation, better gain flatness, higher stability, and lower noise figure;
3.Modules structure,full-duplex & dual-port design, and built-in power supply,easy for maintenance and installation;
4.High linearity PA; high system gain;
5.Allowing for continuous gain adjustment 31dB by 1dB step;
6.ALC technology used to provide auto amplitude fixing;
7.Press-key , Local PC GUI operation and Optional Remote Modem control.

When received by the repeater, the downlink signals from BTS will go through the duplexer, which acts to filter out the out-band spurious, and then further through low-noise amplifier, and power amplifier, reach the repeat end, where signals are passed to antenna through duplexer, and emitted to the whole covered area, thus completing a round of downlink channel function.
When the repeat antenna receives uplink signals from a subscriber, the signals will undergo processing of low-noise amplifier, filter and power amplifier first, and then be transmitted to the base station, thus accomplishing connection between subscribers in signal blind area and base station.
In this way, the blind areas are eliminated.
Considering receiving signal intensity and coverage size may vary with sites where repeater is located, it is necessary to control the gain and output of the repeater.
Additionally, considering the fading effect in spatial signal transmission, auto amplitude fixing for output is required.
For this purpose, MGC and ALC circuits are included in the uplink/downlink channels.
