S20F Series Single Band Digital Band Selective Repeater

Product Features:


Adopting industrial grade electronic components, with stable performance 

  and long working life;

With superior aluminum radiator and excellent heat dissipation, rapid cooling 

  of the working temperature of FPGA to extend the     device’s service life;

Well-designed and strictly controlled, the device’s RF index is better than similar products;

With high-precision OLCD display screen, device’s working status and parameters can be

  clearly shown;

With operating buttons, easier operation and maintenance, supporting checking and setting 

  on the device without PC or laptop;

Sub-band number and bandwidth can be set among the range of 200KHz~20MHz;

Precise manual gain attenuation, with 1dB step to attenuate the gain among 1-31dB range;

Dynamical and precise ALC to ensure stable UL&DL signals.

       With the Development of mobile telecommunication technology, mobile operators feel pinch of the spectrum resource so that previous 2G spectrum has been re-matched and used for 3G 4G network. However, theearlier analog repeaters are with fixed and preset frequency as well as bandwidth, which can not meet mobile operators’ requirements for re-matching frequency and band-width.

        Amplitec’s digital repeaters adopt the latest digital filtering technique, transmitting analog RF signal into digital signal. This technology makes it possible that the number of sub-bands as well as frequency and bandwidth of each sub-band can be flexibly set with software in the digital domain, which allows mobile operators’ or system integrators’ requirements on flexible configuration to be met in practice with efficiency.
