This fully funded PhD position at Chalmers University of Technology focuses on developing nonlinear power-efficient transmit array architectures. The research addresses limitations in current transmitters regarding bandwidth, energy efficiency, and linearity by exploring innovative approaches at the intersection of antenna design, circuit design, and signal processing. The project leverages antenna mutual coupling for effective amplitude modulation, aiming to overcome traditional challenges and foster sustainable digital transformation. The position is hosted by the Microwave Electronics Laboratory at MC2, providing access to state-of-the-art MMIC foundry processes and world-class measurement infrastructure. You will join a vibrant research environment with five other PhD students working in related areas, offering ample opportunities for collaboration and peer learning. The research involves designing microwave components such as power amplifiers and antenna arrays, as well as developing theoretical models for energy-efficient transmission. The goal is to create a scalable transmitter architecture that utilizes mutual antenna coupling for load modulation, enabling efficient signal creation similar to classical Chireix outphasing but using the antenna aperture as the combining element. Facilities include the Kollberg lab, renowned for its advanced microwave measurement capabilities. The project benefits from collaboration agreements with semiconductor manufacturers, allowing fabrication in CMOS, GaAs, and GaN processes. As a doctoral student, you will pursue both coursework and research, develop scientific concepts, and communicate your findings at international conferences and in high-impact journals. The position typically includes 20% departmental work, mainly teaching duties, and is limited to a maximum of five years. Applicants must hold a master's degree (or a 4-year bachelor's degree for non-Swedish education) in Electrical Engineering, Communication Engineering, Engineering Physics, Computer Engineering, or a related field, with a strong background in electronic circuit design. Proficiency in English, both written and verbal, is required. Experience in integrated and high-frequency circuit design, antennas, wireless communication systems engineering, analog circuit design, advanced courses in microwave circuit design and signal processing, and familiarity with tools such as Cadence Virtuoso, MWO, Keysight ADS, SPICE, Matlab, as well as high-frequency RF and measurement equipment, will strengthen your application. Physical presence throughout the study period and a valid residence permit by the start date are mandatory. Chalmers offers a dynamic and inspiring working environment in Gothenburg, Sweden, with generous employee benefits, including parental leave, subsidized day care, free schools, and healthcare. The university is committed to gender balance, equality, and inclusion, and provides Swedish language courses for international students. The starting salary is 35,725 SEK per month (from May 1, 2026), and the position is fully funded from the outset. To apply, submit your application in English as PDF files via the online application form. Required documents include your CV, personal letter, introduction, motivation, thesis, and transcripts. Incomplete applications and those sent by email will not be considered. References will be requested after the interview. The application deadline is August 16, 2026.

Chalmers University of Technology is advertising a postdoc in Nonlinear Power-Efficient Transmit Array Architecture within the Microwave Electronics Laboratory at MC2 in Gothenburg, Sweden. The project sits at the intersection of antenna design, circuit design, and signal processing . It focuses on developing novel nonlinear multi-antenna transmitters that improve bandwidth, energy efficiency, linearity, frequency performance, and power handling by exploiting antenna mutual coupling as a means of amplitude and load modulation. The work aims to challenge the traditional view of coupling as a drawback and instead use it to create a scalable transmitter architecture inspired by outphasing concepts such as Chireix, with the antenna aperture acting as the combining element. The successful candidate will work in a complementary research team and contribute to the design of microwave components such as power amplifiers and antenna arrays, as well as the theoretical derivation of optimal feeding strategies for the individual amplifiers. The position is hosted at the Department of Microtechnology and Nanoscience, with access to advanced microwave measurement facilities at the Kollberg lab and to a strong research environment at MC2, which includes collaboration with Swedish and international partners and a large micro- and nanofabrication cleanroom. The project is supported by collaboration agreements with semiconductor manufacturers, enabling fabrication in CMOS, GaAs, and GaN processes. The role includes independent research, publishing results, co-supervision of PhD students, and preparation of reports for funding agencies. Applicants must hold a doctoral degree in Electrical Engineering, Communication Engineering, Applied Physics, or an equivalent field. Teaching experience and strong research potential are expected. Background in wireless systems, analog circuit design, microwave circuit design, and signal processing will strengthen the application. This is a full-time temporary postdoc appointment for two years , with the possibility of a one-year extension. Physical presence is required throughout the appointment, and a valid residence permit must be shown by the start date if applicable. The deadline for applications is 2026-08-16 .
