Working Principle
The principle of GSM850MHz Wide Band Repeater is the downlink signal received by the Donor Antenna of the base station shall be sent to a band selective filter via duplexer to be filtered and to be amplified by the downlink band selective amplifier to a proper level. The Coverage Antenna via a duplexer shall emit the downlink signal. Similarly, the signal received by the Re-transmission Antenna shall have its level adjusted to a regulated level by a uplink band selective amplifier after it is filtered. The Donor Antenna will emit it after it is filtered and sent to the duplexer
WCDMA 3G mobile signal amplifier Kingtone 3G WCDMA frequency:1920~1980 2110~2170MHz cellular signal repeater/amplifier 3G 2100
Main Features:
1.High linearity PA
2.High system gain
3.Intelligent ALC technology
4.Full duplex and high isolation from uplink to downlink
5.Automatic opearation convenient operation
6.Integrated technique with reliable performance.
7.Bandwidth can be configured from 0.2-25MHz in work band.
8.Local and remote monitoring (optional)with automatic fault alarm & remote control
9.Weatherproof design for all-weather installation.
Application:
To expand signal coverage of fill signal blind area where signal is weak or unavailable.
Outdoor:Airports,Tourism Regions,Golf Courses,Tunnels,Factories,Mining Districts,Villages etc.
Indoor:Hotels,Exhibition Centers,Basements,Shoppingg Malls,Offices,Parking lot etc.
It is mainly applicable to such case:
The repeater can find an instalation place which can receive pure BTS signal at strong enough level as the Rx level in repeater site should be more than -70dBm.
And can meet the requirement of antenna isolation to avoid self-oscillation.

The Pole should be strong fixed on the ground, especially the outdoor installation. The scratches occurred in transit should be paint for protection, to prevent corrosion of the equipment.
When grounding, securely connect with the building or the surrounding grounded objects to minimized damage caused by lightning.
Repeater to be installed at least 60cm from ground and at least 50cm from the wall, to make the equipment easy to heat. Front of the equipment is better to North.
