What can you learn from acoustic wave filter market leaders?

Radio design is characterized by tighter module integration with increased number of filters, switches, antenna tuners, and directional couplers. Supporting 5G adds a different set of challenges for RF front-end (RFFE) design, for example:

• There is a 5× increase in the number of frequency bands and combinations that need to be covered by 5G.
• The increase in the number of antennae results in more design complexity.
• The co-existence of Wi-Fi and 5G means that both wireless technologies must be supported without interference.

RF filters are a key element in developing the RF front end (RFFE) system-in-package (SiP) needed for 5G. Acoustic wave filter die demand is projected to grow 12% year over year, resulting in an increase of 123 billion from 2020 to 2025. (“Acoustic Filters: Critical to Future RFFE integration”, TechInsights). The crucial role of filters for RFFE design combined with market demand create a timely opportunity that market leaders (i.e., Qorvo, Qualcomm, Skyworks, etc.) and disruptors (i.e., Akoustis) want to capitalize on.
