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.

About connector_type choices:
  • Single: the bump connects the two sides

  • GSG: ground-signal-ground indium bumps

  • Coax: signal transmitting bump is surrounded by four ground bumps


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

PCell parameters:

  • connector_type (String) - Connector type, default=Coax, choices=['Single', 'GSG', 'Coax']

  • 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
