About me

My name is Eduard Heidebrecht and I’m a passionate RF engineer. This passion brought me to my PhD, which I received from the chair of High Frequency Electronics at RWTH Aachen University in Germany. There, I also did my bachelor’s degree in electrical engineering and my master’s degree with a focus on information and communication technology.

Throughout my research journey, I’ve delved into a variety of areas including:

• Parametric amplification and frequency conversion in CMOS
• Coupled mmWave oscillators
• Modelling of passive and active components
• Design automation of RF circuits
• Novel Doherty power amplifier (PA) architecture in various technology nodes (CMOS, GaN MMIC, hybrid) and frequencies

The Doherty PA is also the centre of my PhD thesis. Alongside this, I’m highly interested in radar systems, and as a side project, I am developing a MIMO radar system for teaching purposes.

Besides my main research in the RF domain, I also contributed to an interdisciplinary project called upBUS. The aim of upBUS was to provide a seamless handover of a driving cabin between a shuttle bus and a cable car system. For that, I developed high-precision positioning sensors based on sonar, integrated the electronics into the driving module, and developed the precise exchange procedure which was supported by sensor fusion.

During my research, I gained a strong intuition for technical problems. I strongly believe that good intuition on a topic makes it much easier to develop expert knowledge of it. From my own experience, I can tell that one needs more than lectures and exercises to gain intuition. There must be an interaction with the topic: visually and experimentally. This website is my attempt to provide such an experience, in which I will discuss RF topics guided by interactive visualizations, aiming to foster a deeper connection to the subject for enthusiasts and professionals alike.
