Summer positions at The Microwave Electronics Laboratory

Information about the laboratory
The Microwave Electronics Laboratory (MEL) is the largest out of eight laboratories at the Department of Microtechnology and Nanoscience. At MEL we are more than 40 people performing world-class research on high speed electronic components, circuits, and systems for a wide range of communication, industrial, and remote sensing applications in the frequency range from 1 GHz to 500 GHz and beyond. Our facilities include a uniquely well-equipped laboratory for advanced millimeter wave measurements.

The division is now recruiting four full-time summer positions, and you find more information about each of them below.

#1 Artificial intelligent (AI) assisted circuit design for 6G communications

Job description
A significant aspect of our research focuses on addressing the increasing demand for higher capacity and enhanced energy efficiency in future wireless communication systems. We are currently exploring innovative wideband, linear, and highly efficient circuit solutions for 6G communication systems. One of our primary research objectives is to develop a new generation of power amplifiers with AI-assisted, deep learning-enabled design capabilities that can be scaled to meet the requirements of such applications.

Qualifications
We are looking for a person with a genuine interest in deep learning and radio frequency circuit design. Your work will oriented around advanced AI-assisted energy-efficient power amplifier (PA) solutions. You will perform simulation-based pre-studies of innovative Doherty PA solutions using trained artificial neural networks. This will be complemented with comparison of existing, already fabricated Doherty PA circuits. To qualify for this role, you should have completed MSc or BSc courses in circuit design. Proficiency in programming languages such as Python or MATLAB is essential. Experience in machine learning/deep learning is highly advantageous, as is familiarity with circuit design tools like the Advanced Design System (ADS).

#2 Circuit board delevoplent for 6G testbed

Job description
We are looking for a person with genuine interest in getting hands-on experience with microwave electronics, as well as getting valuable knowledge in tranceiver design. The work will be focused on the development of a testbed that is used for demonstrating a new architecture, relevant for 6G. Specifically, you will complete the design of a circuit board in ADS, which will be used as tranceivers in the testbed. When the design is finished, it needs to be assembled and tested.

Qualifications
To qualify, you should have completed courses in analog circuit design, preferrably for microwave components.

#3 Nonlinear Varactor Characterization

Job description
We are looking for a person with a genuine interest in nonlinear device characterization, microwave measurements, and modelling. You will characterize different types of novel varactors based on nonlinear dielectrics (Barium Strontium Titanate - BST). You will use static S-parameter measurements at different bias levels as well as two tone measurements. You will then analyze the obtained measurement data and use it to build a nonlinear device model an a microwave simulator tool (ADS or MWO). You will then perform additional large signal measurements and validate your model based on those measurement results.

Qualifications
To qualify, you should have MSc courses in microwave electronics. Experience in microwave measurement systems and device modelling is beneficial. You have experience in writing Matlab code and preferrably instrument control.

#4 Development of a VNA based Power amplifier characterization setup

Job description
We are looking for a person with a genuine interest in microwave measurement equipment and circuit characterization. Your assignment will be to develop a vector network analyzer based high-power automated characterization setup for Power amplifiers. The goal is to perform power sweeps with the network analyzer while triggering current meters to measure the complex gain, power consumption, and efficiency of the PA effectively for different frequencies and supply voltages. Your task will involve the selection of microwave components like directional couplers and amplifiers, physically building the test setup, and controlling everything through a computer using GPIB and LAN. You will also create a matlab environment that allows future researchers to use this tool in an effective way and document the whole system in a report.

Qualifications
To qualify, you should have MSc courses in microwave electronics. Experience in microwave measurement systems is beneficial. You have experience in writing Matlab code and preferrably instrument control.
