Modelithics, Cree Collaborate To Make New LDMOS Library Available To High-Power Designers

Tampa, FL and Sunnyvale, CA -- Modelithics and Cree Microwave announce the availability of a library of high accuracy non-linear models for a family of LDMOS power transistors manufactured by Cree Microwave. These models have been produced as part of an agreement between the two companies under which Modelithics has been contracted to develop, distribute, and support high accuracy electro-thermal non-linear LDMOS models for multiple popular microwave simulators. The models are based on a new LDMOS non-linear model called the Cree-Modelithics-Curtice (CMC) model, developed in collaboration between Cree Microwave, Modelithics, and W.R. Curtice Consulting in 2003.

Larry Dunleavy, president of Modelithics, noted:"The relationship with Cree is a great example of how Modelithics is partnering with device suppliers for the benefit of the design community. The creation of these models was a very successful collaboration that has produced an excellent library of high power electro-thermal/non-linear transistor models that have high accuracy, are easy to install and use and come complete with documentation by way of data sheets for all the models. These models will initially be available through the Modelithics website at no charge to users."

John Quinn, VP for Cree Microwave, stated: "Partnering with Modelithics, Inc. enables Cree Microwave to provide highly accurate models for a large number of the devices in its LDMOS RF Power Transistor product range. These models enable our customers to design and evaluate circuit and system level performance with a level of accuracy not previously available, substantially shortening design time and reducing risks in the entire design process. In contrast to previously available industry large-signal models, the CMC models have significantly improved accuracy in predicting device performance over a wide range of conditions including Class A/B for high linearity applications as well as deeper back-off (Class B and E) for more novel circuit approaches."

The new models for CreeMicrowave's LDMOS technology also operate over wider bandwidths allowing accurate simulations of amplifier intermodulation and harmonic performances. The initial Cree-Modelithics library supports the Advanced Design System and Microwave Office simulators provided by Agilent Technologies and Applied Wave Research, respectively. Alternative simulator library creation, support and customer service is provided by Modelithics.
