S-Parameter Data and Circuit Models

API Technologies Inmet S-Parameter Data and Circuit Models

Modelithics Global Models™ Substrate Scalable Models

These measurement-based models, available for selected lnmet Brand PowerFilm™ devices, are for use with microstrip applications. The models account for printed circuit board related parasitic effects and are substrate scalable, in that substrate height, dielectric constant, loss tangent, and solder pad terminal dimensions are input parameters. Each attenuator series model is dB value scalable and the resistor models are available for a variety of ohm values.

Each model includes complete documentation detailing the test fixtures used, measurement conditions, range of validity, and model-to-measurement data comparisons.
