RF Material & 50Ω Microstrip Selector

Pick your frequency and substrate height — get a laminate recommendation and an approximate 50Ω trace width. Estimates only; PCBark confirms against a field solver.

Microstrip width from Wheeler/IPC-2141 approximation for Z₀≈50Ω. Real impedance depends on copper roughness, plating and solder mask — always verify with your fab. Source: IPC-2141 / Rogers design Dk values.
