Advanced RF Competence & Applications

This pages provides an overview of the advanced RF competencies that we use regarding measurement & characterization techniques, transistor modelling and EM-field simulations as well as application examples.

Characterization

of devices & circuits, discrete & on-wafer, DC (continous, pulsed), RF small- & large-signal measurements, wideband-modulated measurements

Transistor Modeling

small-signal, large-signal & noise-modeling of GaN HEMTs & InP HBTs, high-frequency switching, HEMTs in AlN & strained GaN technology

EM-Field Simulations

modeling of passive elements in integrated circuits (GaN, InP), packaging & multi-chip modules, sub-mm wave transmission lines, calibration algorithms

We use our microwave know-how to push the limits of electronics also in fields beyond the classical portfolio. This includes quantum technologies, optoelectronics and special industrial microwave applications.
