United States

MODELITHICS INC. is a leading-edge technology company providing comprehensive RF/MW measurement services, and highly scalable, accurate, measurement-based models of RF/MW components. Over 575 models from over 65 vendors, representing more than 15,000 components are now available in Modelithics libraries, which install as specialized design kits in popular EDA software (Keysight ADS, Keysight Genesys, NI/AWR Design Environment, ANSYS HFSS and Sonnet Suites).

Modelithics models capture complex characteristics and parasitic effects of RF and MW components and designs. They offer scalable design parameters to allow accurate matching to designers' applications.  This increases first-pass design success, thus noticeable cost savings.

Modelithics COMPLETE includes the CLR Library of Microwave Global Models™ (passives), NLD Library (non-linear diodes), NLT Library (non-linear transistors), and SLC Library (system-level components). Also included is an S-parameter data model library (SPAR) and a substrate definition library (SUB).

Modelithics was established in 2001 and is used by RF and MW designers around the world in a broad range of industries. We support RF component and semiconductor device manufacturers by developing top quality models for their products.

Automation and Real-time Verification of Passive Component S-parameter Measurements Using Loss Factor Calculations

An automated S-parameter testing approach, built around a LabVIEW program, is described that adds important capabilities to a microwave test setup. A real-time check on S-parameter data using total loss calculations is shown to be a good indicator of m...
In developing microwave models, real-time verification of characterization data should be considered a priority to ensure its integrity. Sound models must be built upon accurate measurement data, and, as is generally the case, the ‘garbage in – garbage out’ principle applies to model extraction. Even if an instrument calibration...
