RF System Expert

This role is focused on world-leading Radio Unit (RU) solutions. The prime objective is R&D within RU system. The areas of the research comprise: 5G RF solution research, including 5G low-frequency and 5G high-frequency massive MIMO active antenna systems (AASs). RU system algorithm analysis, such as: DPD, CFR, SRC, ICS, CPRI etc.
RF key technology and sub-system research, such as: antenna calibration, timing and synchronization etc. RU system architecture analysis, including logical and physical architectures.


This position requires you to be an expert in RF-Systems and to have very strong skills in modelling and simulations. You are expected to have the ability to track latest technical trends in RF systems. We hope you have more than 10 years’ experience in RF systems. Hands-on experience in designing and characterizing RF building blocks as well as building RF test beds is a must. Familiar with RF measurement instruments, e.g. VNAs, spectrum analyzers, vector signal generators, and oscilloscopes. In-depth knowledge on massive MIMO AASs is a plus. Previous experience of telecom/ base station systems timing and synch aspects, including time and frequency distribution, oscillators and PLLs is also a plus. A PhD Degree in a relevant area is of course a merit.

Required skills/personal characteristics
The right candidate must be open-minded and eager to share knowledge, ideas and experiences with colleagues and should have a proven capability to pursue creative solutions.
