Technical features

1)  Receiving and sending separation, low require for Ant isolation, making it convenient for installation

2)  Mini design with metal cavity filter technology inside

3)  Waterproof chassis suitable for indoor and outdoor service

4)  Metal cavity filter technology inside, which gives wider receiving and sending separation, better gain flatness, higher stability, and lower noise figure

5)  Full-duplex & dual-port design, and built-in power supply, making it convenient for installation

6)  Allowing for continuous gain adjustment and gain contrast

7)  ALC technology used to provide auto amplitude fixing

8)  Power, uplink and downlink output indications

9)  Module structures, making it convenient for installation, debugging and maintenance

 

 

Working  Principles

 

1)       When received by the repeater, the downlink signals from base station will go through the duplexer, which acts to filter out the out-band spurious

2)       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

3)       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

4)       Thus accomplishing connection between subscribers in signal blind area and base station. In this way, the blind areas are eliminated

5)       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

6)       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
