skrf.tlineFunctions.zl_2_total_loss(z0, zl, theta)[source]

Total loss of a terminated transmission line (in natural unit).

The total loss expressed in terms of the load impedance is [1] :

\[TL = \frac{R_{in}}{R_L} \left| \cosh \theta + \frac{Z_L}{Z_0} \sinh\theta \right|^2\]
Parameters:

  • z0 (number or array-like) – characteristic impedance.

  • zl (number or array-like) – load impedance

  • theta (number or array-like) – electrical length of the line (may be complex).

Returns:

total_loss – total loss in natural unit

Return type:

number or array-like
