Modelithics®, the leading provider of high-accuracy RF and microwave simulation models, announced that new high-power GaN models from Guerrilla RF, a leading provider of high-performance radio frequency (RF) and microwave semiconductors — have been added to the Modelithics COMPLETE Library™. These new nonlinear models were developed through Guerrilla RF’s collaboration with Modelithics via the Sponsoring MVP (Modelithics Vendor Partner) Program.
The first set of models is now available for the following devices: GRF0010 – 15 W PSAT, GRF0020 – 30 W PSAT, GRF0030 – 50 W PSAT, GRF0065 – 80 W PSAT, GRF0090 – 110 W PSAT, and GRF0135 – 150 W PSAT. Models for additional power variants will continue to roll out over the course of the next few months.
The availability of these models marks the final step in commercializing Guerrilla RF’s new GaN-on-SiC HEMT product line. All devices listed above are in production and readily available for purchase. For customers who depend on nonlinear models as a core part of their design process, these new additions are expected to significantly reduce overall development time and hence accelerate design-in activity.
“Market consolidation and competitor exits have created a real gap in high-power GaN — and Guerrilla RF exists to fill it. The surge in demand we’re seeing for drone, counter-drone, and tactical radio applications requires ultra-wideband power amplifiers that perform without compromise. Our GaN-on-SiC HEMTs — spanning 5 W to 150 W, supporting 28 V and 50 V, and fully EAR99 compliant — were designed from the ground up to meet that challenge. Partnering with Modelithics to deliver these nonlinear models isn’t just a technical milestone — it’s the final unlock that gives engineers worldwide the design confidence to commit to GRF GaN and accelerate their programs. Becoming a Modelithics Sponsoring MVP and releasing these models puts the full modeling infrastructure in engineers’ hands, so they can reduce costly prototype iterations and accelerate fielding of the systems our warfighters and commercial customers depend on.”, Ryan Pratt, CEO & Founder, Guerrilla RF.
Modeling Specifics
As part of the Sponsoring MVP collaboration, Modelithics has completed the development of six new nonlinear GaN HEMT models for Guerrilla RF devices, now available to designers worldwide within the Modelithics COMPLETE Library™:
These high-accuracy models are validated against measured broadband multi-frequency S-parameters and large-signal load-pull data, enabling designers to confidently simulate broadband RF power amplifier performance across a wide range of bias, frequency, and thermal conditions.
The new models leverage the Modelithics-Enhanced Angelov nonlinear formulation and include advanced features such as scalable bias control, electro-thermal self-heating effects, and intrinsic voltage/current sensing for waveform-based RF power amplifier design. They support 28 V to 50 V operation and are validated over relevant RF power and frequency ranges, making them well suited for applications including aerospace and defense, infrastructure, test and measurement, and industrial RF systems. These models are part of a growing Modelithics library for Guerrilla RF products, which also includes a large list of amplifier behavioral models.
“I’m excited to release these new Guerrilla RF GaN models in Modelithics COMPLETE Library™. This welcome collaboration is producing more of the up-to-date, high-demand content we aim to support for the RF design community. We are pleased to have Guerrilla RF expand their engagement with Modelithics through the Sponsoring MVP program and look forward to adding to the model portfolio as additional devices are released.”, Larry Dunleavy, President & CEO, Modelithics.
The new models are available now in both Keysight Advanced Design System (ADS) and Cadence® AWR Design Environment simulators and may be accessed through the Modelithics COMPLETE Library™, as well as via 90-day free trial access of the entire Modelithics Guerrilla RF sub-library, including the new GaN HEMT models along with models for many other Guerilla RF Products.
