Using an online impedance calculator gets you quite far: https://www.eeweb.com/tools/microstrip-impedance Put the numbers in and you'll see the problem with the 2 layer design. Note that if you order 4-layer prototypes, you need to carefully check the manufacturer's website for the actual stack-up, to get the actual number for the layer separation. It can be as low as 0.1mm, or as much as 0.25mm. This affects the required trace width. It's still not perfect; for really accurate impedance, you need to pay extra for impedance controlled PCB manufacturing (meaning more precise process control, so you get accurate track widths). |

Thank you a lot! Do you know where I can order boards of the Rogers high frequency with prepreg material type? |
