Internship | In-situ RF Monitoring and Control of Microwave Power Amplifiers

About this position

Power amplifiers are key components in radar systems. In a phased array configuration, the loading of the power amplifiers varies with transmit angle due to mutual coupling in the antenna elements. As a result, the performance of these amplifiers depends on the transmit angle and will be suboptimal in many cases. The current assignment addresses this issue by real-time measurements of the loading condition of the amplifier and controlling the amplifier settings to optimize the performance for the measured load.

What will be your role?

The first step will be the development of the hardware for real time load monitoring using an already existing integrated microwave power amplifier. This involves the design of for example coupler structures and power and phase detectors. A PCB will be designed on which these detectors are implemented, together with the amplifier to be controlled. A measurement setup will be developed to demonstrate the load measurement and amplifier control in a lab environment. This involves both the hardware setup as well as the software scripts.

What we expect from you

The candidate has the qualities to conduct research in a research environment with the help of specialists from the department. Requirements are: Knowledge of RF (measurements), experience with CAD tools (preferably Keysight ADS) and software scripting (python/matlab).
