20dBm Single Band Selective Repeater

Product Feature:




Light weight, Compact size and high Performance .

Provide quickest solution for indoor signal weak & block zones.

High linear design, low interference to BTS .

Intelligent design, with built-in ALC function, ATT manually attenuation control (1db/step) function.

Coverage area up to 500-2500 m² without block or obstruct.

With the used of IF saw fillter to make it good Out-of-band rejection.

     In mobile communication, it is inevitable that macro-cell coverage cannot cover weak or dead zones; to use repeater is a good choice in these areas. Single band selective repeaters mainly applied in covering small blind and weak zones.
Indoor mini band selective repeater W20B series is a good choice for VIP rooms, offices, houses, restaurants, apartments, packing, etc.
     Indoor mini band selective repeater W20B series enhances consumer satisfaction greatly with its integrated design, compact size, easy engineering and rapid installation and debugging. Indoor mini band selective repeater W20B series is made with the characteristics of industrial aesthetic design, and thus can be installed in high-class places as a decoration.
     SAW filter technology enables it to amplify only the targeted operator’s signals and reject all the others effectively, it is, therefore, an optimal solution for coverage extension.
