Microwave Acoustic Filters for Wireless Communications: Recent Developments and Innovations

Speaker: Prof. Amelie Hagelauer, Co-Director of the Fraunhofer Research Institution for Microsystems and Solid-State Technologies, Technical University Munich

Abstract

For 30 years the success of microwave acoustics, mainly in mobile phones, has been unstoppable. A lot of effort has been spent to reduce the number of SAW/BAW devices, or ideally, completely remove them. However, no competitive technology providing the same performance at the same size and cost exists today. Thus, the trend is going in the opposite direction, driven by the demand for ever higher data rates and the desire to use the same phone in all parts of the world. The number of acoustic wave devices in a mobile phone is increasing with each new generation of communication standards. In this talk recent developments and innovations for microwave acoustic filters are presented. Those developments are novel architectures, new materials and advanced modeling techniques.

Bio

Prof. Amelie Hagelauer received the Dipl.-Ing. degree in mechatronics and the Dr.-Ing. degree in electrical engineering from Friedrich-Alexander-University Erlangen-Nuremberg, Erlangen, Germany, in 2007 and 2013, respectively. Since 2013, she has been focusing on SAW/BAW and RF MEMS components, as well as on microwave integrated circuits for frontends. From 2016 to 2019, she led a Research Group on electronic circuits and from August 2019 to September 2021 she was Full Professor at the University of Bayreuth, Germany. In September 2021, she joined the Technical University Munich as Full Professor and became the Co-Director of the Fraunhofer Research Institution for Microsystems and Solid State Technologies EMFT. She has been engaged in research and development of microwave theory and technology, electronic circuits and systems, and communication and sensing systems. In these fields, she has authored or coauthored more than 140 peer-reviewed publications.

Future trends in RF and wireless test capabilities from 5G to 6G and beyond

Speaker: Charles Schroeder, NI Fellow

Abstract

Measurements, and the science behind them, are key to the design of modern electromechanical systems. And while the devices we’re designing are evolving rapidly, the instruments making these key measurements of performance have been slower to evolve. In general, the size of the instruments we all use hasn’t changed in decades. And the internal architectures, still heavily reliant on PC-based hardware and software components, have reached their limits. It’s time for a re-thinking, not just of the hardware and software architectures of instrumentation, but of how instruments are used as a part of the design process.
