class pmrf.models.utility.Measured(ntwk: skrf.network.Network | str)

Bases: Model

Parameters:

ntwk (Network | str)

s_measured: Array

f_measured: Array

s(freq)

Scattering parameter matrix.

If only a() is implemented, converts via pmrf.functions.conversions.a2s().

Parameters:

freq (Frequency) – Frequency grid.

Returns:

S-parameter matrix with shape (nf, n, n).

Return type:

jnp.ndarray

Raises:

NotImplementedError – If neither a nor s is implemented in a subclass.

class pmrf.models.utility.SModel(s=<function SModel.s>, *, name=None, separator='_', _z0=(50+0j), _param_groups=<factory>)

Bases: Model

Overview

A general model defined by a constant S-parameter matrix.

Parameters:

• s (array)

• name (str | None)

• separator (str)

• _z0 (complex)

• _param_groups (list[ParameterGroup])

s(freq)

Returns the S-parameter matrix.

Args:

freq (Frequency): Specifies the frequency to calculate the parameters at.

Returns:

jnp.ndarray: The resultant block-diagonal S-parameter matrix.

Parameters:

freq (Frequency)

Return type:

Array

a(freq)

Returns the ABCD matrix.

Args:

freq (Frequency): Specifies the frequency to calculate the parameters at.

Returns:

jnp.ndarray: The resultant block-diagonal ABCD matrix.

Parameters:

freq (Frequency)

Return type:

Array
