DirectionalCoupler

class pmrf.models.components.ideal.DirectionalCoupler(coupling: Array | ndarray | bool | number | bool | int | float | complex, *, z0: complex = 50 + 0j, name: str | None = None, metadata: Any = None)

Bases: Model

An ideal 4-port tunable directional coupler.

Port routing: - Port 1: Input - Port 2: Through - Port 3: Coupled - Port 4: Isolated

Parameters:

coupling (ArrayLike) – The linear voltage coupling factor. This is not a tunable parameter by default. To specify a free parameter, use a constructor from pmrf.parameters. For example, for a 20 dB coupler, coupling = 10**(-20/20) = 0.1.
