Introduction

The Component feature is built upon the high accuracy de-embedding technique1 used for Sonnet co-calibrated internal ports technology. Using this technique, the user can insert an ideal element, measurement of a physical component, a data file created by another Sonnet project, another Sonnet project or a user model from a Modelithics library. In addition, using the Component feature in conjunction with the Keysight ADS Interface, Cadence AWR Microwave Office Interface, or the Cadence Virtuoso Interface provides a powerful tool to model complex circuits.

The Components features allows for a high level of flexibility by using five different Component types:

•  Data File type: If you would like to insert an S-parameter data file of your component into your Sonnet model.
•  Ideal type: If you would like to insert an ideal component (R, L, or C) into your Sonnet model.
•  Ports Only type: If you would like to use a separate circuit simulation tool for the final, combined simulation, you may insert only ports within the Sonnet model.
•  Sonnet Project: If you would like to insert another Sonnet project into your Sonnet model.
•  User Model: If you would like to insert a model from another source into your Sonnet model.

In all cases except where the Ports Only component types are used, the Sonnet solver uses a circuit simulation technique to produce the combined results. Since this is a post EM analysis step, the user can change the ideal component value, or associated S-parameter data file, Sonnet project or Modelithics model without requiring a new EM analysis; only the circuit simulation part of the analysis is performed by the analysis engine.

Please note that the coupling from the inside of the component to the rest of the circuit is not considered in the Sonnet analysis. Only the coupling from the component’s terminals is considered.

When connecting external parts to your EM structure, we highly recommend that you use either the co-calibrated ports or the Component feature. This novel approach provides greatly enhanced accuracy for this application by perfectly de-embedding the ports, thus completely removing all coupling between them. Delta gap ports have the limitation of not removing any port to port coupling.

Before proceeding to use the Component feature, it would be helpful to become familiar with the related co-calibrated internal ports discussed in Co-calibrated Internal Ports.
