Job description

Project Overview

Current transmitters are limited in terms of their bandwidth, energy efficiency, and linearity. In this research project you will work on 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 the Research Facility

The position is hosted by the Microwave Electronics Laboratory at Chalmers University of Technology. The laboratory provides access to state‑of‑the‑art MMIC foundry processes and world‑class measurement infrastructure, and currently 5 students pursue their Ph.D. in related areas, offering ample opportunities for collaboration and learning.

Research Project Details

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, and to derive the theory for feeding the individual amplifiers to achieve the most energy‑efficient transmission in a specific direction. The goal is to develop a scalable transmitter architecture that embraces mutual antenna coupling as a means of load modulation, allowing neighboring elements to efficiently create modulated signals that leverage the antenna aperture as a combining element. The project is supported by collaboration agreements with semiconductor manufacturers that allow fabrication in CMOS, GaAs, and GaN processes.

Who We Are Looking For

Mandatory Requirements

• Master's‑level degree (at least 240 higher education credits) in Electrical Engineering, Communication Engineering, Engineering Physics, Computer Engineering, or a related field, with a strong background in electronic circuit design.
• Strong written and verbal communication skills in English.

Desired Skills and Experience

• Experience in the design of integrated and high‑frequency circuits as well as antennas.
• Specialization in wireless and/or wireless communication systems engineering and/or analog circuit design.
• Advanced courses in microwave circuit design.
• Advanced courses in signal processing.
• Experience with Cadence Virtuoso, MWO, Keysight ADS, SPICE, and 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 Doctoral student include pursuing your own doctoral studies, conducting 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, mainly teaching duties. The employment is limited to a maximum of five years.

Contract Terms

The Doctoral student position is fully funded from the start and is a fixed‑term appointment of four years, with the possibility to teach up to 20%, which can extend the position to five years. The starting salary is 35,725 SEK per month (valid from May 1, 2026). Doctoral studies require physical presence throughout the entire study period. A valid residence permit must be presented by the study start date; otherwise admission may be withdrawn.

Benefits

As a Doctoral student at Chalmers, you are an employee and enjoy all employee benefits. The dynamic and inspiring working environment is located in the coastal city of Gothenburg, and the university is dedicated to improving gender balance and supporting diversity and inclusion.
