Some RF PCB layout and routing tips include:
- Use short traces: Minimize the length of traces to reduce signal attenuation and delay.
- Maintain proper impedance: Ensure consistent impedance throughout the layout to avoid reflections.
- Separate high-frequency and low-frequency traces: To prevent interference.
- Employ shielding: Around sensitive components or areas to block external interference.
- Optimize via design: Keep vias small and spaced appropriately to minimize their impact.
- Manage power and ground planes: Make them continuous and well-distributed.
- Be cautious with component placement: Consider signal paths and interference.
- Use controlled impedance laminates: For better signal quality.
- Avoid sharp bends in traces: As they can cause signal distortion.
- Account for thermal effects: Especially for high-power RF components.
- Perform electromagnetic compatibility (EMC) checks: To ensure compliance.
- Label and document clearly: For easier troubleshooting and maintenance.
