Research Topics

Our research is focused on microwave electronics.

We are currently addressing the following topics.
Concerning the details, please refer to our publications.

Transistor Modelling

  • large-signal,
  • small-signal, and
  • noise modeling  (1/f and white noise)


  • hetero-bipolar-transistors (GaAs, InP, SiGe)
  • hetero-fieldeffect-transistors (GaN, GaAs)

Low-Noise Amplifier
The focus is on highly linear or highly robust low-noise amplifiers in GaN technology.

Our main partner is the Ferdinand-Braun-Insitut, Leibniz-Institut für Höchstfrequenztechnik, at Berlin-Adlershof.
