Note:

The Following guidelines are recommended for implementation of the RF design:

  • Ensure an RF path is designed with an impedance of 50 Ω
  • Tuning of the antenna impedance π matching network is recommended after manufacturing of the PCB to account for PCB parasitics
  • π or L matching and tuning may be required between cascaded passive components on the RF path
