I am researching the high linearity in frequency converters up to 300 GHz. Therefore, I am currently working with gallium nitride (GaN) circuits. Using the models and the technology from Fraunhofer IAF, I build frequency converters and mixers at around 140 GHz. This contributes to having more efficient circuits at higher frequencies, which can be used in communications, for example.
There are a lot. (Laughs.) One major point is the intense guidance we receive from Dr. Sébastien Chartier and Professor Rüdiger Quay. Another point is the fact that we use the technology from Fraunhofer IAF. For example, we are in very close contact with the modelling group and I receive a lot of support from Dr. Dirk Schwantuschke in my work with GaN.
It is a cheerful give and take: We exchange both know-how and infrastructure. For example, when we started setting up the measurement laboratory at INATECH, Fraunhofer IAF advised us very well. In turn, we now provide these setups to our colleagues at Fraunhofer IAF for their own measurements.
I was positively surprised how direct the communication turned out to be. Like with other cooperation partners, we only have external access rights. But in reality, we are in permanent exchange with the researchers of Fraunhofer IAF and we constantly visit each other. That is really nice! There is no better way to learn.
Above all, we can benefit from the collaboration we have already done and each other’s strengths. Between both institutions, the focus is not on competition, but the transfer of knowledge and helping each other. This common foundation is a huge advantage.
