When routing high speed traces (5GHz+) on a PCB, what are the best practices to mitigate unwanted noise and improve signal integrity? Please list these in order from most beneficial to least.
1. Increase trace widths to reduce electrical resistance and inductance.
2. Space traces apart to reduce crosstalk.
3. Utilize ground and power planes to reduce noise and improve signal integrity.
4. Utilize vias and stitching capacitors to reduce impedance and control signal reflections.
5. Utilize termination resistors to reduce signal reflections.
6. Utilize shielding and RF filtering to reduce EMI.
7. Utilize impedance controlled differential pairs to reduce noise.
8. Utilize transmission line techniques such as routing signals on specific layers to reduce signal skew.
What is the recommended trace width for this task?
