•    Automotive: 5.9 GHz C-V2X and DSRC Acoustic Wave Resonator RF Filter Circuit (US 10,979,023)

In addition to its patent portfolio, Akoustis’ IP includes the ownership of valuable trade secrets associated with manufacturing its proprietary XBAW® BAW high band RF filter products and single crystal piezoelectric materials. 

Jeff Shealy, CEO of Akoustis, commented, “Since we started Akoustis, we believed a significant IP and patent portfolio would ultimately be a key driver of value for our shareholders and other stakeholders. We will continue to invest in innovative IP to create unique RF solutions and to protect our XBAW® BAW technology." 

Akoustis is actively delivering volume production of its Wi-Fi 6 tandem filter solutions, shipping multiple 5G small cell XBAW® filter solutions, delivering initial designs of its new 5G mobile filter solutions to multiple customers and is now entering the market with its new Wi-Fi 6E coexistence XBAW® filter solutions.

Given the rapidly growing sales funnel activity as well as ongoing interaction with customers regarding expected ramps in both 5G mobile and Wi-Fi 6E in calendar 2022, the company plans to double the annual production capacity at its New York fab by the end of calendar 2021.
