Introduction

  Kingtone Bi-Directional Amplifiers system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Bi-Directional Amplifiers system is to receive low-power signal from BTS via radio frequency transmission nd then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted to the BTS via the opposite direction.


Main features

UHF 400-470mhz walkie talkie repeater ,UHF Repeater ,TETRA 450 repeater

Main Features

  • High linearity PA; High system gain;
  • Intelligent ALC technology;
  • Full duplex and high isolation from uplink to downlink;
  • Automatic Operation convenient operation;
  • Integrated technique with reliable performance;
  • Bandwidth can be configured from 0.2-25MHz in work band.
  • Local and remote monitoring (optional) with automatic fault alarm &remote control;
  • Weatherproof design for all-weather installation;
Application Scenarios

UHF 400-470mhz walkie talkie repeater ,UHF Repeater ,TETRA 450 repeater Applications

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, Shopping

Malls, Offices, Packing Lots etc.

It is mainly applicable to such case:

The Bi-Directional Amplifier can find an installation place which can receive pure BTS signal at strong enough level as the Rx Level in Bi-Directional Amplifier site should be more than-70dBm;

And can meet the requirement of antenna isolation to avoid self-oscillation.
