skrf.tlineFunctions.zl_2_zin(z0, zl, theta)

Input impedance from load impedance at a given electrical length.

Input impedance of load impedance zl at a given electrical length, given characteristic impedance z0.

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:

zin – input impedance at theta

Return type:

number or array-like
