Doctoral student in microwave technology - focusing on radio frequency (RF) amplifier with high efficiency and high power output

Sort by publication: 2017-10-09


Uppsala University is a broad research university with a strong international position. The task is to conduct research and education of the highest quality and to cooperate in different ways with society. Our most important asset is all the individuals who, with their curiosity and commitment, make Uppsala University one of the country's most exciting workplaces. Uppsala University has 40,000 students, 7,000 employees and a turnover of 6.5 billion.


The doctoral education takes place in the subject of Technical Physics with a focus on microwave technology, at the Department of Solid State Electronics (FTE) ( ), Department of Engineering Sciences, Ångström Laboratory, with access as soon as possible .


This project will be carried out as part of a collaboration between FREIA and FTE, both of which are active in the Ångström Laboratory. FREIA is an acronym for Facility for Research Instrumentation and Accelerator Development. At the FREIA laboratory, the general focus is on developing particle accelerator technology that can be used in major research facilities, such as CERN, ESRF, DESY, European Spallation Source (ESS), etc.


We offer a varied and exciting research training, in collaboration with well-established national and internationally recognized research institutes. The work will be carried out in close cooperation with major EU industries within the new Eurostars project ENEFRF, and will also include trips to major facilities in the EU and participation in conferences in other parts of the world. In the ENEFRF project, we will, together with industry, develop next generation RF amplifiers for isotope producing cyclotrons. The research will be divided into four main sections: (1) High-efficiency RF power amplifiers involving studies of various topologies, such as Class E and inverters, which are used to maximize efficiency at high power; (2) new RF power splitting techniques and use of FPGAs for digital waveform generation; (3) high-efficiency RF power combiners for solid state power amplifiers and (4) characterization of new semiconductor transistors, including load-pull measurements. Aspects related to the thermal behavior, reliability and lifetime of the transistors will also be investigated.


We are looking for graduates with a Master of Science in Engineering or Natural Sciences. A strong motivation and ability to work individually is desirable, as well as good oral and written proficiency in English is required. Previous experiences from work with RF power amplifiers and FPGA programming are highly credible for this PhD student appointment. Backgrounds in electrical engineering with focus on active microwave components are particularly meritorious.


Holders of doctoral posts must mainly engage in their own postgraduate education. Other service, such as teaching, may be included within the scope of the employment with a maximum of 20%. The PhD candidate has a duration equivalent to four years full-time studies.


Information about postgraduate education can be found on the institution's website and the Faculty of Science and Technology .


Local guidelines for payroll placement apply.


The application should contain a brief description of research interests and relevant experience, CV, copies of diplomas and grades, thesis work (or a draft thereof) and other documents that the applicant wishes to claim. We would like to provide you with reference or refer to letter of recommendation.


Uppsala University values the qualities that even gender distribution and diversity add to the business. We therefore look forward to searching for all sexes and with different birth background, functionality and life experience.


Salary : According to local agreement (Local collective agreement for doctoral students and students).
