850MHz 4g Jio India Booster

Product Detail

The cell phone signal amplifier (professional name: signal repeater) consists of antennas, RF duplexers, low noise amplifiers, mixers, attenuators, filters, power amplifiers, and other components or modules to form uplink and downlink amplification links. 

The basic principle of its work is: using the forward antenna (donor antenna) to receive the downlink signal of the base station into the repeater, amplify the useful signal through the low noise amplifier, suppress the noise signal in the signal, and improve the signal to noise ratio (S/N After down-converting to IF signal, filtering by filter, mid-frequency amplification, frequency up-conversion to RF, amplification by power amplifier, transmission by backward antenna (re-send antenna) to mobile station, and using backward antenna Receiving the uplink signal from the mobile station, it is processed along the opposite path by the uplink amplification link: that is, after passing through the low noise amplifier, down converter, filter, intermediate amplifier, up converter, and power amplifier, and then transmitting to the base station. In order to achieve two-way communication between the base station and the mobile station
