Job Description

Date: Nov 9, 2018

Master Thesis @ Ericsson Radio Link Product Development

As a master thesis worker, you will be a part of the Radio Link hardware product development team focusing on developing and maintaining Ericsson’s cutting-edge microwave transport products. Based on thesis scope you will get the opportunity for exciting product development and drive activities such as requirement analysis, design, simulation, integration and verification. We will further offer you opportunities in competence development and gain personal growth as well as get an insight in the great opportunities that Ericsson can offer.


Master Thesis Project Description

The objective of the Master thesis project is to identify requirements and define way-of-working when it comes to electrical and thermal circuit simulations for mm wave products in order to predict circuit hotspots and degradation at the event of electric surge. The thesis work is currently seen to include:

  • Definition and simulation of current and voltage surge cases such as lightning and other events causing electrical and thermal spikes on PCB.
  • Design of reference circuits on which elaborated simulation process(es) will be tested and evaluated.
  • Elaboration of simulation process is to be tested and verified in laboratory environment on defined reference circuits.


Competencies and Qualifications

Core competences for a Master Thesis worker:

  • Studying Master of Science in Electrical Engineering, Engineering Physics or similar
  • Experience in electronics hardware design (analog and/or digital) is seen as a merit
  • Curious and solution-oriented personality
  • Good communications skills (English)



  • All master program courses are preferably finished before start of thesis work
  • The thesis can be done single-handed or in pairs
  • The work should be done in close cooperation with Ericsson AB and follow applicable company standards


Expected Learnings:

The candidate(s) will gain knowledge regarding hardware design requirements for microwave radio links. A deep knowledge within the area of simulation and PCB design principles will be obtained as well as an introduction to working in an agile multicultural environment.

MINI-LINK the Most Popular Microwave Solution in the World

The increasing complexity of today’s and future networks require flexible and well-integrated microwave nodes for mobile backhaul. Building an efficient operator grade microwave backhaul network with end-to-end performance in mind, requires high node capacity, compact and modular building practice, cost obsession and features that respond to demanding customer needs.
