PA Section:
Figure 11 - Schematic PA Section
The PA is supplied by the reader ICs internal voltage regulators. Since the reader ICs internal PA is
not used the corresponding voltage regulator (VDD_PA) is used for the external PA supply. The
power down pin of the external PA is supplied by the VDD_B regulator which is also supplies the 0
dBm output driver of the reader IC. The PA circuitry matches the proposal of the RF2172 datasheet.
