Vacant job

Current transmitters are limited in terms of their bandwidth, energy efficiency, and linearity. In this research project, you will work at the intersection of antenna design, circuit design, and signal processing to investigate novel nonlinear multi-antenna transmitters that overcome these limitations. By utilizing antenna mutual coupling for effective amplitude modulation – a shift from the traditional view that considers it detrimental – you will overcome existing limitations in frequency, efficiency, power, and linearity, thereby fostering sustainable digital transformation.

About us

The position is hosted by the Department of Microwave Electronics (https://www.chalmers.se/en/departments/mc2/research/microwave-electronics/) at MC2 (https://www.chalmers.se/en/departments/mc2/), which 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 1,000 square meter cleanroom for micro- and nanofabrication with the latest equipment.

About the research project

You will work in a complementary team to investigate a new transmitter topology. Your responsibility will be to design microwave components such as power amplifiers and antenna arrays, but also to derive the theory on how to feed the individual amplifiers for the most energy-efficient transmission in a certain direction. The goal is to develop a new scalable transmitter architecture that embraces mutual antenna coupling as a means of load modulation – allowing neighboring elements to efficiently create modulated signals similar to classical Chireix outphasing, but using the antenna aperture as the combining element. The position is hosted at the Department of Microtechnology and Nanoscience where you will have access to state-of-the-art microwave measurement facilities at the Kollberg lab. The project is supported by collaboration agreements with semiconductor manufacturers that allow fabrication in CMOS, GaAs, and GaN processes.

Who we are looking for

The following requirements are mandatory:

• A doctoral degree in Electrical Engineering, Communication Engineering, Applied Physics, or equivalent. This eligibility requirement must be met no later than the time the employment decision is made.
• Strong written and verbal communication skills in English.

You are expected to be somewhat accustomed to teaching and to demonstrate good potential within research and education.

The following experience will strengthen your application:

• Specialization in wireless and/or wireless communication systems engineering and/or analog circuit design.
• Work experience with microwave circuit design.
• Work experience with signal processing.
• It is highly meritorious if the doctoral degree has been obtained within the last three years prior to the application deadline.
• Experience with Cadence Virtuoso, MWO, Keysight ADS, SPICE, Matlab.
• Experience with high-frequency RF and measurement equipment.
• Experience in building RF and microwave systems.
• Experience in microwave and millimeter-wave integrated circuit design.
• Experience with digital signal processing.

What you will do

Your major responsibilities as a postdoctoral researcher are to independently conduct research and publish results, but also to co-supervise some PhD students and prepare reports for funding agencies.

One doctoral student is already working in this area, and you are expected to take on some supervision responsibilities as well and efficiently work on the research question as a team.

The position is meritorious for future roles in academia, industry, or the public sector.

Contract terms

The position is a temporary full-time employment for two years with the possibility of a one-year extension.

The position requires physical presence throughout the entire employment. A valid residence permit must be presented by the start date; otherwise, the offer may be withdrawn.
