 UHF BDA Bi-directional amplifier uhf walkie talkie power amplifier
  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.

Mainfeature

UHF BDA Bi-directional amplifier uhf walkie talkie power amplifier Main Features                              

1. High isolation full duplex design, easy to install.
2. Low noise figure, high receive sensitivity.
3. With ALC and MLC function to ensure stable output power.
4. Low power consumption, environmental protection and energy saving.
5. Modular structure design, easily to upgrade the system.
6. High Q cavity filter and SAW surface acoustic wave filter, high out of band rejection.
7. Adopt the world's most advanced high linearity, low intermodulation LDMOS power amplifier.
8. Adopt the advanced digital PLL, TCXO, OCXO technology, frequency stability and high accuracy.
9. Perfect remote and local network monitoring function.
10. Waterproof design work for all weather indoor and outdoor.

 

 

Application&scenarios

 
UHF BDA Bi-directional amplifier uhf walkie talkie power amplifier 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 repeater can find an installation 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.
