The development of 5G systems promises paradigm-shifting applications while presenting unique challenges across materials, devices, modules, and systems. One area that calls for innovative solutions to support the 5G growth is the front-end acoustic filtering at sub-6 GHz and beyond. To this end, this workshop features a group of international experts who will present upcoming solutions from the industry as well as innovative approaches from academia. The workshop will first highlight system-level considerations and then delve into new materials and enabling device design/modeling techniques before comprehensive solutions that require co-designing devices, circuits, integration, and packaging are discussed. A panel discussion will conclude the workshop with insights and outlooks for the trending acoustic technology candidates as well as the long-term prospects of acoustic devices in RF front ends.
