Current transmitters are limited in terms of their bandwidth, energy efficiency and linearity. In this research project you will work on the intersectional area 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 https://www.chalmers.se/en/departments/mc2/research/microwave-electronics/ at https://www.chalmers.se/en/departments/mc2/ where the you will have access to several commercial state-of-the art MMIC 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.
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 derive the theory 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 combining element. The position is hosted at the department of Microtechnology and Nanoscience where you will haveaccess 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:
You are able to take responsibility, show initiative, and work independently when needed. At the same time, you are a strong team player and enjoy collaborating across disciplines. You have the ability to communicate and disseminate research results effectively to different audiences, including academia, industry, and society.
*for students with an education earned outside of Sweden, a 4-year Bachelor’s degree is accepted.
The following experience will strengthen your application:
What you will do
Your major responsibilities as Doctoral 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 at international conferences and in writing (publishing in highly ranked journals). In addition, the position will normally include 20% departmental work, mostly teaching duties. The employment is limited to a maximum of five years.
