DirectionalCoupler

class pmrf.models.components.ideal.DirectionalCoupler(coupling: Array | ndarray | bool | number | bool | int | float | complex, *, name: str | None = None, metadata: Any = None, z0: Any = 50.0)

Bases: Model

(experimental) 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.

• z0 (ArrayLike, default=50.0) – The intrinsic characteristic impedance for which the coupler was designed.

coupling: Array | ndarray | bool | number | bool | int | float | complex

The linear voltage coupling factor.

z0: ndarray = 50.0

The intrinsic characteristic impedance of the physical device.
