RECEIVERMCUK991001G8 Section 5 Issue 1Technical Guide – 17 – Revision 0The DC level at the output of the Op Amps is 1.35 V with a 200 mV p-p single ended AC swing sufficient to drive the basebandVEGA. The coupling between the RF output and the baseband output has been designed as DC coupling in order to minimisethe turn-on time of the Rx IC.5.3.3 GSM 900 Signal LevelsThe signal levels through the receiver IC for the GSM 900 band are given below.Figure 5.2: GSM 900 Nominal and Worst Case Signal Levels5.3.4 GSM 1800 Signal LevelsThe signal levels through the receiver IC for the GSM 1800 are given below.Figure 5.3: GSM 1800 Nominal and Worst Case Signal Levels-120.0-110.0-100.0-90.0-80.0-70.0-60.0ANTSW I/PSW I/P SAWI/PLNA SAW2I/PMIXI/PIF FILTERI/P2ndMIXER I/PAMP I/P(dBm)Typical CaseWorst Case10155-1-120.0-110.0-100.0-90.0-80.0-70.0-60.0ANTSW I/PSW I/P SAWI/PLNA SAW2I/PMIXI/PIF FILTERI/P2ndMIXER I/PAMP I/P(dBm)Typical CaseWorst Case10156-1
