MRFU - GSM Radio Filter Unit MRFU (GSM Radio Filter Unit) is designed based on multicarrier technology RF Filter Unit, a MRFU module maximum complete 6 carriers. MRFU module is mainly to complete the baseband and RF signal modulation signal demodulation, data processing, shunt, and other functions. › Using direct frequency conversion technology in the transmission channel, the signal is modulated to GSM emission bands amplified with filter, the duplexer filter to the antenna. › The antenna receives the radio signal, the received signal is down converted to intermediate frequency signal, and amplifying processing, analog to digital conversion, digital down converter, matched filter, AGC (Automatic Gain Control) is sent to BBU for processing. › CPRI interface clock generation, loss of CPRI interface clock recovery and alarm detection, and other functions. › Support functions of DPD/BPD predistortion. › Power control, forward power detection. ...
