RF PCB Layout and Routing Tips

Some RF PCB layout and routing tips include:

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