Developing and exploiting new multi-physics measurement techniques for devices for future 5G/6G communication systems

The aim is to improve multi-physics measurements of microwave power transistors, which play important roles in mobile phone infrastructure, satellite communications, terrestrial broadcast, avionic and weather radar systems, to name but just a few applications.

We are currently seeking to fill two PhD positions in the area of multi-physics measurements of microwave power transistors. These transistors play important roles in mobile phone infrastructure, satellite communications, terrestrial broadcast, avionic and weather radar systems, to name but just a few applications. Ever increasing market demands for increased power and efficiency requires accurate measurements under specific realistic conditions. For the successful realization and application of these devices based on e.g. GaN, LDMOS, and GaAs technologies, we need to consider a comprehensive view of the inevitable coupling that occurs between device physics, electromagnetics and the thermal environment. 

The project is hosted in n3m-labs, a multi-physics characterisation laboratory for microwave semiconductor devices, in collaboration with the National Physical Laboratory, the UK's National Metrology Institute. The laboratory is very well equipped with unique measurement capabilities for measuring electric fields and thermal imaging of microwave devices and circuits while they are in operation. 

The students will contribute to the development of a multi-physics measurement platform to measure power transistors, power-amplifiers and antennas under realistic conditions. Which will take into account the requirements on future 5G/6G communication systems. You will closely collaborate with academic and industrial partners in the research programme activities. 

The supervisory team for the two students consists of Dr Koen Buisman and Dr Radu Sporea. Our expertise covers microwave and mm-wave devices and circuits including measurements thereof (Buisman), and semiconductor devices and their characterisation (Sporea). External supervision will be provided by the National Physical Laboratory. We have a track record of publishing our results in high impact journals, and we anticipate the work that you do will generate this level of excitement.
