Focus Microwaves - Cardiff Behavioral Model Software
The Cardiff Model+ formulation has a number of unique benefits over alternative approaches where formulations are truncated. Once the formulation is extended, the model moves away from a local model, where multiple models are required to define an impedance space (i.e load lookup), to a model that has a set of coefficients that describes the behavior of a device over an entire impedance space. This dramatically reduces file size and also allows any interpolation to be defined by the model itself rather than relying upon the interpolation algorithm in the simulator. Also, as harmonic superposition is not assumed in the CM+ formulation, a full harmonic mixing model is uncovered describing harmonic interactions and improving model accuracy particularly for complex modes of operation.

The Cardiff Model portfolio is fully supported in all major EDS tools including Keysight Advanced Design System and AWR Microwave office. These models are ideal for release to customers. They are accurate and as they are black box no reverse engineering of the underlying technology is possible.
