    Amplitec S27T series digital mobile signal repeater is used to extend mobile providers' networks. These repeater are  cellular solutions with easy installation, which enable operators to improve signal coverage without establishing new BTS. The repeater is adjusted strictly to the bandwidth at which mobile provider performs. It support 3 sub-bands and up to 12 channels per customer’s request. In case it’s necessary to change the band frequency, the user can easily do it thanks to the SDR technology in the digital repeater.
     The repeater has Digital IF SAW filter technology. Support 3 sub-bands and each bandwidth is with maximum 24MHz.
It can upgrade the underlying FPGA code with the help of the upper software to change the frequency-selecting and band-selecting mode, and it also can make a flexible configuration to the parameters, such as the operation bandwidth and so on.
It can be controlled and monitored, via RS232 connecting PC for local control, via GSM modem connecting PC for remote control, set the frequency and ATT of UL or DL, check the output power of UL or DL, and check the temperature alarm and ALC alarm via the OMT.
