This calculator determines the reflection coefficient (Γ) of an RF circuit from the load impedance (ZL) and the line characteristic impedance (Z0). It makes it possible to evaluate the proportion of the reflected signal in the event of impedance mismatch, essential for analyzing the performance of a transmission network.
Formula
Γ = (ZL − Z0) / (ZL + Z0)
Explanation of the formula
The reflection coefficient (Γ) represents the ratio between the reflected voltage and the incident voltage. If ZL is equal to Z0, Γ = 0, which indicates perfect adaptation. If the difference between ZL and Z0 increases, the absolute value of Γ approaches 1, signifying significant reflection of the signal.
Uses of the calculator
- Evaluate impedance matching in RF transmission lines.
- Analyze the performance of antennas and filter circuits.
- Optimize connections to reduce signal loss through reflection.
- Essential tool for telecommunications engineers and RF system designers.
