The Department of Microtechnology and Nanoscience focuses on research, innovation and education within the fields of future electronics, photonics, bio- and nanosystems. A close collaboration with Swedish and international partners within academia, industry and society enables scientific excellence and creates an innovative environment. In addition to the 200 researchers and PhD students, MC2 houses a cleanroom for micro- and nanofabrication with the latest equipment.Project description
Telecommunication is one of the key enablers of our modern society. With the lower frequency bands getting congested and the increasing push for higher absolute bandwidths that are not available there, frequencies beyond 6 GHz become more relevant for future communication systems. Efficient spectrum utilization further pushes for massive MIMO and beam steering transmitters, enforcing multiple compact transmitters in at a single radio site. For transmitters in these bands beyond 6 GHz but below true mmW frequencies the best solutions in terms of transmitter architectures, transistor technology, number of transmit elements and power levels per channel are currently unknown. Gallium Nitride (GaN) based high electron mobility transistors (HEMTs) grown on silicon carbide (SiC) have become the technology of choice for many RF and microwave power amplifiers in the last years, these devices are quite costly and have undesirable features prohibiting their use in some applications. We now see the advent of the improved second generation of GaN microwave devices, with some exciting developments for cost effective GaN on Si technology.
The goal of your research is to enable compact, cost effective transmitters with higher signal fidelities and power efficiencies than currently possible. Your research will develop new circuit concepts, compare different technologies, and provide a better understanding of the benefits and limitations of second generation GaN devices. The research may thus have strong impact in the realization of future wireless systems for communication and sensors, as well as medical and scientific applications.

Information about the division and the department
The position is hosted by the Microwave Electronics Laboratory at MC2 where the PhD student will have access to several commercial, state-of-the-art MMIC and IC foundry processes and world-class measurement infrastructure allowing for a successful completion of this research project. At the Microwave Electronics laboratory currently 5 students pursue their Ph.D. in a similar area, which plenty of opportunity to collaborate and learn from and with peers. You will also be an important part of a cross-disciplinary and international team of PhD students and senior researchers that perform research on future communication systems, ranging from component to system level

Major responsibilities
Your major responsibilities as PhD student is to pursue your own doctoral studies, including both coursework and research. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing. In addition, the position will normally include 20% departmental work, mostly teaching duties. The employment is limited to a maximum of five years.

Qualifications
To qualify as a PhD student, you must have a master's level degree corresponding to at least 240 higher education credits in a relevant field.
A suitable background for this position is a Master of Science in Electrical Engineering, Communication Engineering, or Engineering Physics with specialization in microwave electronics. Further, experience from RF circuit design, high frequency and microwave measurements, and/or advanced signal processing are important merits.
Since communication of research results is a central part of the work, communicative skills in English (oral as well as in writing) are vital. Furthermore, it will also be expected that you can take on responsibility, take own initiatives and work independently when needed. At the same time it is important that you are good at working in teams. Finally, you need to be able to disseminate results and knowledge within existing and new networks. This includes academia, industry and society at large.

Contract terms
Full-time temporary employment. The position is limited to a maximum of five years.
