5 mm Package

Model Description
The PKG-BAI-QFN5532-001 is a simulation based equivalent circuit model of Barry Industries P/N QFN5532-050x molded 5 mm Quad Flat No lead (QFN) surface mount package. Ansys HFSS 3D simulation
data was used to create model. Simulation results and model validated against measured data to 40
GHz in multiple measurement environments.
Additional package information is available atwww.barryind.com.
