What We Do

Create Accurate Software Models

We create equivalent circuit software models that enable "Rapid circuit prototyping" for use in RF and Microwave design software. Drag and drop our software models into a project or workspace and experience the benefits of substrate and part scalable measurement based models.

Our Model Library software product is available for use with Keysight Technologies' PathWave Advanced Design System (ADS), Cadence AWRDE®, Keysight Technologies' PathWave RF Synthesis (Genesys) , Ansys® HFSS™, Sonnet® Suites™ and Cadence® Spectre® RF Option and Keysight Technologies PathWave System Design (SystemVue).

Characterization and Modeling Services

High quality, rapid turnaround, RF/microwave characterization and modeling services of transistor, diode, passive and system block components.

This innovative technology characterizes the amplitudes and relative phase of harmonics, characterizes impedance mismatches, and can be applied to transistor modeling as an alternative to traditional compact equivalent modeling.

Models on Demand

Careful measurement and extensive knowledge of current EDA tools allow us to create precision models for passive and active components that yield accurate simulations and speed your product development.


Model library planning, applications of accurate models for reducing design time and other requirements for your project.

Characterization Services

Our extensive array of test and measurement equipment, plus years of experience, allow us to measure an extremely wide variety of component and system parameters, including: S-parameters, IV characteristics, load pull, and noise parameters.
