Evaluation of GaN technology in power amplifier design

In this contribution the features of GaN technology for power applications will be explored from the designer point of view. Therefore, the active device will be studied as a black box using its simplified model and putting in evidence the role of its key parameters such as the knee voltage, the breakdown voltage, etc. At the end, the experimental results of several power amplifiers designed using different strategies will be presented to highlight both, the capabilities and/or drawbacks of such material
