The Electromagnetic System Division at DTU Space invites candidates for a PhD position with the aim to develop InP DHBT based sub-THz front-end integrated circuits with performance surpassing that of CMOS/SiGe BiCMOS based circuits. The position is a part of the Smart Networks and Services Joint Undertaking project “X Transceivers & RF front-ends made in Europe's Microelectronics light house to Enable new 6G use cases (X-TREME 6G)”. X-TREME 6G relies on a unique industry led consortium to provide a foundational open microelectronics platform in Europe with the objective to create and design key disruptive next generation chiplets and chipsets for 6G use cases. The idea is to break-up the full potential of best-in-class Silicon BiCMOS, InP and heterogeneous 3D integration for high capacity radio access technologies such as wireless back-hauling at sub-TeraHertz frequencies, Joint Communication And Sensing, Non Terrestrial Networks and Network as a Sensor. New classes of chipsets will unleash the full potential of 6G and enable the emergence of new applications through specific developments for the underpinning novel microelectronic technologies.

Responsibilities and qualifications
Your responsibility will be to design and characterize InP-DHBT-based high-efficiency power amplifiers and low-noise amplifiers at sub-THz frequencies, in the D-band (~150 GHz) and H-band (~250 GHz) with performance surpassing that of state-of-the-art CMOS/SiGe BiCMOS based circuits. This should be achieved by exploiting innovative design techniques and architectures (e.g. gain-boosting strategies and loss-aware power combining/impedance matching schemes), the potential of scaled transistor nodes, benefitting from accurate device models and improvement of sub-THz passives.

For this position you are supposed to work closely together with the technology provider, III-V Lab, and external research stays at III-V Lab are envisioned during the project period.

As part of the Danish PhD program, you will follow a number of PhD courses, supervise B.Sc. and M.Sc. students and contribute to the teaching at the department.

You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

Your required qualifications and skills are:

• Excellent English communication skills both spoken and written.
• Self-motivation in research and innovation.
• A master level education in the field of electrical engineering or physics.

As an ideal candidate, you should also have one or more competences listed below:

• Experience in simulation, design, and layout of high-frequency integrated circuits using tools such as Keysight ADS and Cadence.
• Hands-on experience using commercial electromagnetic simulation tools such as Ansys HFSS and Keysight ADS Momentum.
• Knowledge of semiconductor physics in relation to integrated circuits.
• The ability to work independently while effectively collaborating with both academic and industrial partners in the X-TREME 6G.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see DTU's rules for the PhD education.

Assessment
The assessment of the applicants will be made by Associate Professor Tom K. Johansen.

Furthermore, you have the option of joining our monthly free seminar “PhD relocation to Denmark and startup “Zoom” seminar” for all questions regarding the practical matters of moving to Denmark and working as a PhD at DTU.

Application procedure
Your complete online application must be submitted no later than 27 March 2025 (23:59 Danish time).

Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply now", fill out the online application form, and attach all your materials in English in one PDF file. The file must include:

• A letter motivating the application (cover letter)
• Curriculum vitae
• Grade transcripts and BSc/MSc diploma (in English) including official description of grading scale

You may apply prior to ob­tai­ning your master's degree but cannot begin before having received it.

Applications received after the deadline will not be considered.

All interested candidates irrespective of age, gender, disability, race, religion or ethnic background are encouraged to apply. As DTU works with research in critical technology, which is subject to special rules for security and export control, open-source background checks may be conducted on qualified candidates for the position.

DTU Space is a renowned international institution. From space we explore both the climate on Earth and the distant galaxies of the universe and much more. We also develop instruments and other technology for this purpose. We train engineers and provide research-based advice for the benefit of people.We use satellites, spacecraft, drones and aircraft and carry out measurements on land and at sea in connection with our research and development of technology. We are involved in the entire process from the first scientific idea until an instrument is sent into space to collect data that the scientists analyze and publish.

DTU Space are approximately 230 researchers, PhD students, experts and other staff.

• We collaborate with, among others, the space organizations ESA and NASA, high-tech companies such as Terma, GomSpace and Skywatch and universities such as MIT, Caltech, Yale, Max Planck Institute and the University of Surrey Space Centre.
• We cooperate with authorities in Denmark, Greenland and the Faroe Islands.
• We present our knowledge in approximately 200 scientific publications annually, at conferences and with presentations to decision-makers and other stakeholders, as well as via the media to the population as a whole.

III-V Lab (www.3-5lab.fr) is located in Palaiseau (Paris area), France, III-V Lab is a joint venture between Thales, Nokia and CEA​​ consisting of around 150 researchers, ​
