2.3 Overview of RF Droop Correction Measurements

This section explains how to use and enable the RF droop correction in AFE8092. Figure 2-1 shows a common RF circuit and the tap-off points from where the input measurements can be taken. If Meas1 tap-off point is chosen, the RF droop introduced until the output of Matching Network is corrected. If Meas2 tap-off point is chosen, the RF droop introduced until the output of Power Amplifier is corrected.

Either the M1 and M2 can be measured at Meas1 or at Meas2.
