9 Power Supply Recommendations
TI recommends placement of bypass capacitors close to the pins. Consult the EVM instructions for layout examples. If fractional spurs are a large concern, using a ferrite bead to each of these power supply pins can reduce spurs to a small degree. This device has integrated LDOs, which improves the resistance to power supply noise. However, the pullup components on the RFoutA and RFoutB pins on the outputs have a direct connection to the power supply, so extra care must be made to ensure that the voltage is clean for these pins.
