PCB Microstrip Crosstalk

Estimates the crosstalk coupling between two adjacent microstrip traces using: Xtalk = 20 × log₁₀(1 / (1 + (s/h)²)), where s is the trace spacing and h is the substrate height. Result is in dB — more negative means less crosstalk.

Inputs

Edge-to-edge spacing between adjacent traces in millimetres

Height of the dielectric substrate in millimetres

Results

Substrate height must be greater than zero
