Ferdinand-Braun-Institut

The Ferdinand-Braun-Institut, Leibniz-Institut für Höchstfrequenztechnik (FBH) is a research institute, which is a member of the Gottfried Wilhelm Leibniz Scientific Community.

The institute is named after Ferdinand Braun (1850–1918), who received the Nobel Prize for physics in 1909 for his contributions on the development of wireless telegraphy.

Services from the FBH comprise e.g. prototyping of electronical and optoelectronical GaAs and GaN based devices, epitaxy of GaAs-based layer systems, the development of GaAs processes, pilot series of integrated microwave circuits and laser diodes, consulting in rf measurement technology and the simulation of coplanar waveguide circuits.

Here some examples: In 1999, employees of the FBH founded Three-Five Epitaxial Services AG (TESAG), a company to produce semiconductor layer systems which acts as basis for devices like laser diodes, LEDs, transistors (HBTs) or Schottky-Diodes.

In 2006, BeMiTec was founded to develop, produce and sell high-power gallium nitride transistors (GaN) for future applications in mobile communications.

This was followed in 2016 by the spin-off of UVphotonics working with ultraviolet LED, 2017 BeamXpert: the company offers simulation software for optical systems.
