Grounding Strategy :
- Implement continuous ground planes beneath RF sections
- Use multiple vias to connect ground pads to the reference plane
Thermal Considerations :
- Provide adequate copper area for heat dissipation (minimum 2mm² per pad)
- Avoid placing near heat-generating components (>3mm spacing recommended)
