Calculates the absolute load impedance, reflection coefficient, VSWR, return loss and mismatch loss of a load.

Enter the source characteristic impedance and the load impedance then press "Calculate" below.

The absolute value of the load impedance is calculated from the complex impedance (R + j).

Where R is the Real part of the impedance

and j is the Imaginary part of the impedance

The Load Reflection Coefficient ( Γ ) is calculated using the complex impedance of the load and the characteristic impedance of the source.

Where Zo is the Source Impedance

The VSWR is then calculated using the Reflection Coefficient

The Reflection Coefficient is used again to calculate the Return Loss

The Reflection Coefficient is used yet again to calculate the Mismatch Loss

Various equations for Voltage Reflection Coefficient and VSWR are also available at:-
