3.2 General Layout Recommendations
Ensure that the following general layout recommendations are followed:
• Have a solid ground plane and ground vias under the module for stable system and thermal dissipation.
• Do not run signal traces underneath the module on a layer where the module is mounted.
3.3 RF Layout Recommendations
The RF section of this wireless module gets top priority in terms of layout. It is very important for the RF section
to be laid out correctly to ensure optimum performance from the module. A poor layout can cause low-output
power, EVM degradation, sensitivity degradation, and mask violations.
