PCB Microstrip Crosstalk Calculator

Trace Spacing
Substrate Height

Assess the extent of unwanted coupled energy between traces by considering trace spacing and substrate height.

Utilize this online electrical calculator to ascertain microstrip crosstalk on a Printed Circuit Board (PCB) using trace spacing and substrate height as parameters. Crosstalk pertains to undesired coupled energy between traces and can be classified as forward or retrograde.

PCB Microstrip Crosstalk formula

    \[CTdb = 20\log_{10}\left(\frac{1}{1+\left(\frac{S}{H}\right)^2}\right)\]


  • CTdb = CrossTalk
  • S = Trace Spacing
  • H = Substrate Height
