The Microwave Electronics Laboratory at Chalmers University of Technology, Sweden, is inviting applications for a postdoctoral researcher position in Integrated Circuits for Full-Duplex Communication and Sensing. This opportunity is part of classIC, the Swedish Multidisciplinary Research Center for Semiconductor System Design, and is supervised by Professor Christian Fager. The research targets advanced challenges in modern RF systems, specifically self-interference mitigation for in-band full-duplex MIMO systems. The focus is on developing novel integrated microwave circuit architectures in the 7–20 GHz range, utilizing RFIC/CMOS and MMIC technologies. The successful candidate will join a highly international and multidisciplinary team, collaborating on the co-design of antennas, RF front-ends, and signal processing. The position offers access to world-class measurement facilities at the Kollberg Laboratory, which supports research from DC up to terahertz frequencies and is renowned for its advanced instrumentation and open research environment. The laboratory's infrastructure enables cutting-edge research in wireless communications, radar sensors, and space exploration, with applications in autonomous vehicles and high-frequency systems. Responsibilities include conducting high-impact research, contributing to publications, supervising PhD students, and shaping future research directions in high-capacity communication and sensing. Applicants should hold a PhD in Electrical Engineering, Microwave Electronics, Integrated Circuits, or a related field, with experience in RFIC/CMOS and MMIC technologies, and knowledge of full-duplex communication and MIMO systems. A strong publication record, teamwork skills, and proficiency in English are required. This is a fully funded postdoctoral position at Chalmers University of Technology. The application deadline is January 31, 2026. For more information and to apply, visit the official Chalmers vacancies page or the provided application link. This position is ideal for candidates interested in integrated circuits, microwave electronics, semiconductor system design, and advanced measurement technology.

Join the Microwave Electronics Laboratory (MEL) at Chalmers University of Technology as a postdoctoral researcher and contribute to cutting-edge research in integrated circuits for full-duplex communication and sensing. MEL is one of the largest divisions within the Department of Microtechnology and Nanoscience, with over 40 researchers working on high-speed electronic components, circuits, and systems for communication, industrial, and remote sensing applications across 1 GHz to 500 GHz and beyond. The laboratory offers state-of-the-art facilities for advanced microwave, millimeter wave, and sub-terahertz measurements. This postdoctoral project focuses on developing novel integrated microwave circuit architectures to address the challenges of in-band full-duplex (IBFD) operation in MIMO systems, particularly the mitigation of self-interference. The research will target the 7–20 GHz frequency range and involve both RFIC/CMOS and MMIC implementations. You will have access to advanced semiconductor technologies and world-class measurement facilities at the Kollberg Laboratory. The project is highly collaborative, involving experts in antennas, RF circuits, and digital signal processing, aiming for co-optimized solutions to maximize full-duplex MIMO performance. As a postdoc, you will conduct independent and collaborative research, lead and co-author scientific publications, participate in joint activities with academic and industrial partners, and contribute to the supervision of PhD and MSc students. The position is full-time for two years, with the possibility of a one-year extension, and requires physical presence in Gothenburg, Sweden. Chalmers offers a dynamic and inclusive work environment, comprehensive employee benefits, and support for international staff, including Swedish language courses. Applicants must have a PhD in electrical engineering, engineering physics, or a related field, with strong expertise in RF/microwave engineering, analog/RFIC design, and/or MMIC design. Experience with circuit simulation and layout tools (e.g., Cadence, ADS, HFSS) and high-frequency measurements is highly valued. Proficiency in English and excellent interpersonal skills are essential. The application deadline is January 31, 2026.
