Nitronex and Modelithics have announced a collaboration to create state-of-the-art nonlinear models for Nitronex’s high power gallium nitride (GaN) devices. Combining the Modelithics team’s 35+ years of modeling experience with Nitronex’s industry-leading GaN power devices will allow power amplifier designers to achieve best-in-class performance with faster time to market....

Modelithics Inc. announced the release of its latest version of the Modelithics CLR Library™ of reliably accurate and highly scalable models for AWR’s Microwave Office® software. Ted Miracco, Executive Vice President or AWR Corp., remarked, “AWR customers have successfully used the Modelithics’ CLR Library to improve product performance and...

Pad scalability corresponds to the ability to change the dimensions of the bonding or solder pad used for attachment of a surface mount component. In this paper, a new pad scalability feature added to selected Global Models contained in Modelithics CLR Library[1,2] is discussed. We demonstrate the excellent correlation...

A library of robust models featuring substrate scalability and temperature dependence is now available for surface-mount diodes. The Modelithics Nonlinear Diode (NLD™) Library contains a compilation of measurement validated nonlinear diode models developed from I-V, C-V, small- and large-signal S-parameter characterization data. Over-temperature testing, combined with Modelithics’ patent-pending substrate-scalability...

Powerfully flexible software models are now available for surface-mount (SMT) resistor, inductor and capacitor (RLC) components that are accurate over wide ranges of frequency, part value and mounting configurations. These unique, substrate-scalable Global Models™ are developed from careful measurements taken in typical application circuit mounts on multiple boards. Global...
