Circulator

Model ideal frequency-independent circulators with S-parameters

  • Library:
  • SimRF / Circuit Envelope / Junctions

Description

Use the Circulator block to model ideal passive three-port circulators in a circuit envelope environment. Circulators are used to control signal direction and flow inside an RF circuit. The Circulator block can circulate the signal in clockwise or counterclockwise direction depending on the parameter selection.

Parameters

expand all

Circulator direction, specified as:

  • Circulator clockwise

    The default option is Circulator clockwise. The s-parameter matrix for Circulator clockwise is:

    [001100010]

    Circulator counter clockwise

    The s-parameter matrix for Circulator counter clockwise is:

    [010001100]

Reference impedance of circulator, specified as a scalar or three-tuple vector.

Select this parameter to ground and hide the negative terminals. To expose the negative terminals, clear this parameter. By exposing these terminals, you can connect them to other parts of your model.

By default, this option is selected.
