4.5 WBZ35x Module RF Considerations
The product design, environment and application significantly affect the overall performance of the system. The product designer must ensure system-level shielding (if required) and verify the performance of the product features and applications.
The following are the guidelines to consider for optimal RF performance:
- Position the WBZ35x Module in a noise-free RF environment, keep it far away from high-frequency clock signals and any other sources of RF energy.
- Do not shield the antenna by any metal objects.
- The power supply must be clean and noise-free.
- Ensure that the width of the traces routed to GND, VDD rails are sufficiently large for handling peak TX current consumption.Note: The WBZ35x Module includes RF shielding on top of the board as a standard feature.
