S-Parameter Data and Circuit Models

Powerfilm logo TM white.png

These measurement-based models, available for select 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.
