Passive Plus Inc. (PPI) announced the release of new Modelithics models for the R35-1209BB and R35-2010BB flip-chip resistor products. New Microwave Global Models™ for both resistor series are now available within the Modelithics COMPLETE Library™ as well as the Modelithics mmWave & 5G Library. In addition, new 3D geometry models for the resistors are now available within the latest version, v20.8, of the Modelithics COMPLETE+3D Library for Ansys HFSS™.

The new Microwave Global Models are for resistor values of 50 and 100 Ω and are validated to 60 GHz, making them well suited for today’s higher frequency requirements. The models provide validated data for a range of substrates and scale with respect to solder-pad dimensions.

In addition, new 50 and 100 Ω 3D electromagnetic models are available for both the R35-1209BB and R35-2010BB resistor series. These models, available within the Modelithics COMPLETE+3D Library for Ansys HFSS, are also validated to 60 GHz, making them well suited for broadband applications.
