Supply modulated PAs: promises and challenges

This introductory talk will set the scene for the workshop by identifying the applications for which supply modulated techniques can provide the breakthrough in efficiency performance for the power amplifier, including mobile and mobile infrastructure, radar and EW systems, and space transmitters. At the same time, the talk will give an honest assessment of the challenges still slowing down the use of supply modulated techniques in high frequency PAs, for which the following talks will provide interesting solutions.
