class kqcircuits.elements.flip_chip_connectors.flip_chip_connector_rf.FlipChipConnectorRf[source]

Bases: Element

PCell declaration for an inter-chip rf connector.

Flip chip connector with two coplanar waveguide connections and different ground bump configurations. The input port is on the first face and on the left. The output port is on the second face and rotated as chosen.


Child classes re-define this method to build the PCell.

classmethod get_sim_ports(simulation)[source]

List of RefpointToSimPort objects defining which refpoints should be turned to simulation ports for the given element class

Returns empty list if not implemented for Element subclass. When implementing this method, the best practice is for this method to have no “side effects”, that is all code contained within this method should only serve to derive the list of RefpointToSimPort objects and nothing else: no change in element’s geometry or parameter values.

  • cls – Element class, this is a class method

  • simulation – Simulation object where a cell of this element class is placed. Use this argument if you need to decide certain arguments for RefpointToSimPort objects based on simulation’s parameters


List of RefpointToSimPort objects, empty list by default

PCell parameters:

  • inter_bump_distance (Double) - Distance between In bumps, default=100, unit=μm

  • output_rotation (Double) - Rotation of output port w.r.t. input port, default=180, unit=degrees

  • connector_a (Double) - Conductor width at the connector area, default=40, unit=μm

  • connector_b (Double) - Gap width at the connector area, default=40, unit=μm

  • round_connector (Boolean) - Use round connector shape, default=False

  • n_center_bumps (Int) - Number of center bumps in series, default=1

  • bump_type (String) - Bump type, default=Flip Chip Connector Dc, choices=['Flip Chip Connector Dc']

  • a2 (Double) - Non-physical value ‘-1’ means that the default size ‘a’ is used., default=-1, unit=μm

  • b2 (Double) - Non-physical value ‘-1’ means that the default size ‘b’ is used., default=-1, unit=μm
