Research Internship at IMEC (Leuven, Belgium)


Characterization and modelling of advanced RF transistors for high performance 5G radios



The fifth generation of cellular communication (5G) promises a tenfold increase in data rates and the millimeter-wave (mmWave) spectrum bands represent an opportunity for these extremely broadband mobile communication because of the large available bandwidth at these frequencies. The high manufacturing volumes expected for 5G user equipment devices favor low-cost and high-integrated technologies, which are typically today Si based. Unfortunately, these technologies are un-efficient in mmWave power generation. The current research in the field aims therefore to develop devices which can be manufactured at large scale while capable of generating efficiently mmWave power.

Proposed activity

In this internship, you will characterize and model the advanced transistors developed in imec for 5G mmWave applications. These transistors, while fabricated on a Si platform, are using III-V or GaN materials to enhance the power generation efficiency. You will measure small and/or large signal RF characteristics over a broad frequency range (kHz up to 110GHz). From these measurements, you will complete the transistor models which will serve both to optimize the technologies and to simulate mmWave circuits. You will be part of a research team in imec specialized in the modelling of advanced transistors.

Application info

You must be a student enrolled at the University of Bologna (Bachelor’s, Master’s, or PhD) in the field of electronics, preferably with a background in high-frequency electronics and laboratory test equipment. You must have a good level of written/spoken English (B2 or above). The typical internship duration is from 3 to 6 months. The internship will take place at the IMEC facilities in Leuven (Belgium). If applicable, the activity can be considered as a part of a thesis or PhD activity, to be agreed with the promoter. For additional info and to submit your application, contact the UNIBO supervisor Prof. Alberto Santarelli.
