About PCB Signal Reflection Calculator:
This free PCB Signal Reflection Calculator helps determine signal reflections and losses in high-speed PCB traces due to impedance mismatches.
Formulas Used:
- Reflection Coefficient (Γ) = (ZL - Z0)/(ZL + Z0)
- Return Loss (dB) = -20 × log10|Γ|
- Insertion Loss (dB) = -20 × log10|1 - Γ²|
- Where:
- ZL = Load impedance
- Z0 = Source impedance
- Γ = Reflection coefficient
Design Guidelines:
- Return Loss > 20 dB recommended
- Reflection Coefficient < 0.1 ideal
- Match impedances within 10%
- Consider termination for long traces
