Development of high power amplifiers for radar applications

By Carlos Cilla Hernández

Advanced radar systems have received considerable attention due to the increased demand in remote sensing and imaging applications both for terrestrial and space systems. A key element in this system is the high power amplifier, which has experienced a renewed interest due to the enormous progress in solid-state technology and devices. An emerging technology particularly promising for high power amplifier realization is GaN device technology.

The scope of the PhD project lies in the development of design methodologies, nonlinear modeling, manufacturing, packaging and efficient testing of solid state high power amplifier modules. A further goal is to develop a high power amplifier for X-band frequencies with capabilities to replace the vacuum tubes currently used in commercial radar systems.

Advances in high power amplifier technology will help reducing the system size and cost, and enhancing transmission rates and target detection.
