R629 tells the SW which FEM control should beactive. Renesas FEM control is used when R629 is 18K and RFMD FEM control is used whenR629 is 82K.If the FEM is exchanged with an other type, the R629 has to be changed, too.Renesa FEM logicTable 13: Renesa FEM logicMode Vtx BS VC1 VC2VTX_B_P VTX_B_P Vant1 Vant2Low Band RX 0 0 0 0Low Band TX 1 0 1 0High Band RX 0 1 0 0High Band TX 1 1 0 1MjoelnerN600AttenuatorR714(R711)Z603(T600)R611R610TXC (R620) Max PW 1.6VMin PW 0.6 VTXP (C646) 2.7VOpamp (C644) Max PW 1.2 VMin PW 0.6532.5 dBm(29.5 dBm) + 2 dBm + 4 dBmFEMN700VC1 VC2 VTX BSDetMax PW: 1.13 vdcMin PW: 0.22 VdcVpc R712Max PW: 1.2 VdcMin PW: 0.65 VdcNames in () is for high bandAll the red signals are pulsed with the burstThe Green "DC" signals are pulsed with the burstIn local mode random burst RF signals can be demodulated by a GSMtester
