Barry Industries and Modelithics Develop Broadband 5mm C-QFN Package Model to 40GHz

Attleboro, MA – Barry Industries and Modelithics, Inc. have published a report detailing the broadband performance of Barry's 5mm high temperature co-fired ceramic (HTCC) quad-flat-no-leads (QFN) package to 40GHz. Barry Industries is an ISO9001:2008 certified ITAR-registered manufacturer of high quality thick film resistors, terminations, attenuators and high temperature co-fired ceramic (HTCC) packaging.

The report presents the accurate modeling of each of the 5mm QFNs 32 pins to 40GHz using a combination of Ansys HFSS 3D simulation and precision Modelithics measurement data. The model features 64 ports for the inner and outer connections of each pin and two model package options depending on the design configuration. The Modelithics model is validated with a comparison to actual measured data, including an example fixture with a transmission line mounted and connected with wire bonds in the Barry package.
