skrf.network.Network.from_z

classmethod Network.from_z(z, *args, **kw)[source]

Create a Network from its Z-parameters.

Parameters:

  • z (Numpy array) – Impedance matrix. Should be of shape fxnxn, where f is frequency axis and n is number of ports

  • **kwargs – key word arguments can be used to assign properties of the Network, f and z0.

Returns:

ntw – Created Network

Return type:

Network

Examples

>>> f = rf.Frequency(start=1, stop=2, npoints=4)  # 4 frequency points
>>> z = np.random.rand(len(f),2,2) + np.random.rand(len(f),2,2)*1j  # 2-port z-matrix: shape=(4,2,2)
>>> ntw = rf.Network.from_z(z, f=f)
