PRODUCTION DATA
Figure 8-1 shows an example schematic for PA biasing using a single AFE11612-SEP to bias the GaN and LDMOS PAs simultaneously. In this application, one DAC is used in the positive output range, and a second DAC is used in the negative range through the use of a differential operational amplifier.
