Masterthesis: GaN-Based RF Power Devices & Circuits

At the Fraunhofer Institute for Applied Solid State Physics IAF we know our technologies like the back of our hand. Because we are one of the few scientific institutions worldwide to conduct research along the entire semiconductor value chain and on tailor-made synthetic diamonds. Whether high-frequency circuits for communications technology, voltage converter modules for electromobility, laser systems for measurement processes, or innovative hardware and software for quantum computers and quantum sensors: we develop tomorrow’s technology in-house for a sustainable and secure society. When will you join us?

In our microelectronics department we offer a master thesis in the field of GaN power electronics.

What you do:

Master’s thesis topics in the area of RF power devices and circuits are based on our in-house GaN HEMT technologies and reflect our research interests, which currently include the following areas:

• Packaged / integrated high-power amplifiers with output power levels in the kW-range.
• Integrated power amplifiers (e.g. Doherty PAs, Wideband PAs) for SatCom or 5G/6G.
• Multi-functional transceiver MMICs and their individual building blocks (e.g., LNAs, PAs, mixers, frequency multipliers, phase shifters, attenuators, power detectors, …).
• Design and optimization of active devices (diodes, HEMTs) for emerging applications and frequency bands.
• Characterization and thermal / electrical modeling of active and passive devices.

What you bring along:

• Enrolled student in a physics, electrical engineering or a comparable Master programme
• Interest in challenging scientific content from experiment and theory
• Enjoyment of scientific work
• Ability to work in a team, openness and motivation to work independently and purposefully

What we offer:

• Personal support on an equal footing and assistance from experienced scientists and professionals throughout your thesis
• Modern laboratory equipment in a new laboratory building
• Flexible working hours that fit your studies
• Collaboration in an interdisciplinary team, including participation in current projects with clear objectives
• An open and team-oriented corporate culture that allows you to contribute your own ideas
• Diverse and exciting tasks in the environment of an internationally renowned research institution
• Free parking garage with e-charging stations, as well as a Frelo station (bike rental system) and a bus stop directly at the institute

The position is initially limited to 6 month. The monthly working time is 40 hours.

We value and promote the diversity of our employees' skills and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, as well as sexual orientation and identity. Severely disabled individuals will be given preference if equally qualified.
Our tasks are diverse and adaptable - for applicants with disabilities, we will jointly find solutions that optimally promote your abilities. The same applies if you do not meet all profile requirements due to a disability.
