Comprehensive measurement capabilities and configurable test environments enable precise characterization of devices under application-relevant bias, temperature, and frequency conditions.
Modelithics offers flexible measurement capabilities and can develop custom hardware, software, and high-power test solutions to address unique device characterization requirements.
Advanced measurement benches deliver precise, repeatable characterization data to support accurate model development and simulation.
VNA platforms cover the sweep to 170 GHz standard and higher on request. Mixed-mode designs get true 4-port measurement through 67 GHz.
Noise parameters run to 50 GHz, with noise figure and 1/f flicker noise. The screen room around the bench minimizes local interference.
Automated tuners sweep the impedance plane, and the contours map output power, PAE, transducer gain, 1 dB compression and IM3.
Transistor and diode IV families under DC and pulsed bias, high power pulsed IV to 30 A, so self-heating and trapping stay visible.
The sweeps repeat across the operating range, so you see how far the S-Parameters and IV curves move with temperature.
Advanced instrumentation, proven methodologies, and custom test solutions enable Modelithics to deliver accurate characterization data across a wide range of technologies and operating conditions.

Modelithics documents its released models down to the measurement conditions and the typical range of validity. Characterization data goes out to that same standard, in file formats a simulator reads directly.

Insights from teams achieving accurate, reliable RF and microwave designs
I have used Modelithics models for almost 10 years when designing high power amplifiers operating from low MHz to 6GHz and spanning power levels from 5W to 1KW and have had great success in the predicted performance that these models offer over standard S-Parameter models. These models have aided in our single iteration success when moving from the paper design to the bench.
I have been using Modelithics CLR models for close to 20 years now in my development of High-Power Doherty Amplifiers. I have found that without these models my design cycle time is negatively impacted due to extra design spins required from empirical tuning. Utilizing Modelithics models greatly aids in reducing my design cycle time and limits the amount of board spins required.
Thank you very much for all of your assistance in setting up the Modelithics libraries. Your service is top notch and you should be very proud of it!
Thanks you for helping us create great designs – faster and with a higher level of quality! Modelithics models allowed us to better predict performance and correct any deficiencies prior to final component selection and prototype fabrication. Yields were also improved as designs were better centered.
We recently had an excellent experience working with Modelithics on a project to characterize and model pHEMT devices. The model provided exceeded our expectations in terms of non-linear prediction against load-pull data and robustness of convergence in our Simulator. It was a nice bonus to receive it well ahead of schedule as well. We would readily recommend Modelithics and plan to use their services again in the future when additional needs arise.
We are at the point where most MMIC designers won’t do the design unless there is a Modelithics model. [The foundry’s] models work for common circuits. But, for more complex requirements, and when we only got one shot we use your models.
While using your models the measured and simulated performance was remarkably similar on the filters I modeled and fabricated – far different from my original simulations. You saved me many, many hours as well as my reputation!
During Design I used [Modelithics Library models ] every day on the block converter project. I also used this to design up to 10 GHz lowpass, highpass, lowpass/highpass combos, bandstop filters, and I never needed to tweak. Got it on first design.
