Terminated

class pmrf.models.composite.interconnected.Terminated(terminated_from: Model, terminated_into: Model, *, z0: complex = 50 + 0j, name: str | None = None, metadata: Any = None, domain_from: str = 's', domain_to: str = 's', method: str | None = None)

Bases: Model

Represents one network terminated in another.

Parameters:

• terminated_from (Model) – The model being terminated.

• terminated_into (Model) – The model that terminated_from is terminated into.

a_in_s_impl(freq: Frequency) → Array

primary_matrix(freq)

The primary matrix (e.g. s, a etc.) as a function of frequency.

The primary matrix represents the matrix returned by pmrf.Model.primary_property, which is either overridden by sub-classes, or is the first proprerty directly overriden out of pmrf.Model.s(), pmrf.Model.a(), pmrf.Model.y(), pmrf.Model.z() (in that order), unless :meth:pmrf.Model.build is overridden, in which case the primary matrix of the built model is returned.

This method can also be overriden itself in order to to dynamically implement one of the matrices as opposed to overriding it explicitly.

Return type:

jnp.ndarray

Raises:

NotImplementedError – If no primary property is overridden.

s_in_s_impl(freq: Frequency) → Array

domain_from: str = 's'

The domain to use for the “from” model. Only ‘s’ is supported.

domain_to: str = 's'

The domain to use for the “to” model. Only ‘s’ is supported.

method: str | None = None

The algorithm to use for the call to terminate_<domain_from>_in_<domain_to>. If None, uses the default algorithm for the domain combination. Algorithms are available in pmrf.rf.

property primary_property

The primary property (e.g. "s", "a") as a string.

The primary property is the first overridden among PRIMARY_PROPERTIES, unless build is overridden, in which case the primary property of the built model is returned.

Return type:

str

Raises:

NotImplementedError – If no primary property is overridden.

terminated_from: Model

The “from” model.

terminated_into: Model

The “into” model.
