2.5 RNWF02 Module RF Considerations

The overall performance of the system is significantly affected by the product design, environment and application. The product designer must ensure system-level shielding (if required) and verify the performance of the product features and applications.

Consider the following guidelines for optimal RF performance:

• The RNWF02 module must be positioned in a noise-free RF environment and must be kept far away from high-frequency clock signals and any other sources of RF energy.
• The antenna must not be shielded by any metal objects.
• The power supply must be clean and noise-free.
• Make sure that the width of the traces routed to GND, VDD rails are sufficiently large for handling peak TX current consumption.
  Note: The RNWF02 module includes RF shielding on top of the board as a standard feature.
