Electronic circuits

Reasearch and development in electronics

Fraunhofer IAF conducts research in both high frequency electronics and power electronics.

In high frequency electronics, Fraunhofer IAF researchers deal with the frequency range up to 1 THz and develop powerful and efficient ICs, devices, modules and sub-systems for applications such as radar sensors and mobile or satellite communications.

In the field of power electronics , Fraunhofer IAF focuses on maximum energy efficiency for electromobility, air conditioning and information technology, novel lateral and vertical 1200 V devices as well as monolithic and heterogeneous integrated circuits.

Fraunhofer IAF is also working on the research and development of new materials, for example aluminum scandium nitride (AlScN) layers for piezoelectric filters.
