5G mobile data transfers require the use of more and higher frequency ranges, all of which need to be accommodated within a single mobile device. Thus, the demands on radio frequency (RF) components are constantly increasing. The Fraunhofer Institute for Applied Solid State Physics IAF has developed novel, compact, and energy-efficient high-frequency / high-bandwidth RF filters to meet those needs. During the project PiTrans, the researchers have managed to grow aluminum scandium nitride (AlScN) with the required industrial specifications and to realize novel electroacoustic devices for smartphones.
