Characterization Services

Modelithics® Inc. provides a broad array of highest quality, RF/microwave/mm-wave characterization services. Modelithics emphasizes wafer probe measurements of semiconductor wafer and chip, as well as surface mount components assembled on hybrid boards. Other measurement configurations involving microstrip or coplanar test fixtures, and measurements to coaxial or waveguide reference planes are available. Among the many measurement capabilities offered, Modelithics can measure s-parameters up to 110GHz standard and even higher frequencies upon request. We offer noise parameter measurements up to 50GHz, load pull, IV, impedance measurements, and more.
