Akoustis Introduces New XBAW Coexistence Filters for WiFi 6E

Akoustis Technologies, an integrated device manufacturer (IDM) of patented bulk acoustic wave (BAW) high-band RF filters for mobile and other wireless applications, has introduced two new WiFi 6E XBAW filter modules that allow for the enhanced use of the 5 GHz WiFi spectrum.

The 5.6 GHz filter module covers the entire UNII 1-3 spectrum and enables an additional 80 MHz and 160 MHz channel in UNII 4, while the 6.6 GHz filter module covers the UNII 5-8 spectrum. Current WiFi 6E configurations allow for the use of six 80 MHz and three 160 MHz channels in the UNII 1-3 spectrum and fourteen 80 MHz and seven 160 MHz channels in the UNII 5-8 spectrum. The new XBAW 5.6/6.6 GHz coexistence filter modules allow for the use of seven 80 MHz and three 160 MHz channels in the UNII 1-4 spectrum and twelve 80 MHz and six 160 MHz channels in the UNII 5-8 spectrum. Given that the 6 GHz portion of the WiFi 6E standard is just beginning to experience utilization, this new XBAW coexistence solution allows for an environment of greater capacity in the 5 GHz bands.

The first order for the new WiFi 6E filters is from a tier-1 OEM that intends to create multi-user, multiple-in-multiple-out mesh routing products for the consumer market. Commercial production is expected in late calendar 2021 to early calendar 2022.

Dave Aichele, EVP of Business Development of Akoustis, said that these new 5.6 GHz and 6.6 GHz WiFi 6E filters provide customers with greater flexibility when choosing RF solutions for next-generation WiFi networking products. Mr Aichele further said that they are excited to have already received their first order for this new enhanced UNII 1-4 XBAW coexistence solution and believe they will continue to see strong momentum with both of their WiFi 6E coexistence filter solutions.

The FCC announced in April of 2020 the approval of 5.9 to 7.1 GHz for unlicensed use, which is the largest spectrum addition since the FCC allocated unlicensed spectrum for WiFi in 1989. The next generation of WiFi that is expected to use these new frequency bands is called WiFi 6E. This approval will create another significant new band, or combination of bands, over the next several years. Since the FCC’s April announcement, governments around the world have begun allocating the same or similar spectrum for future WiFi use. As spectrum is scarce, many nations are limited in the amount of new, available unlicensed spectrum above 6 GHz. This is driving great demand for high-performance coexistence filters that allow the use of all available spectrum.

Akoustis is actively delivering volume production of its WiFi 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 WiFi 6E coexistence XBAW filter solutions. Company management expects continued top-line growth moving forward and given the growing backlog of commercially available RF filter products and technology aimed at large and growing markets, it plans to significantly expand the capacity at its New York fab in calendar 2021.

Akoustis has added 15 filters to its product catalog including a 5.6 GHz WiFi filter, a 5.2 GHz WiFi filter, a 5.5 GHz WiFi 6E filter, a 6.5 GHz WiFi 6E filter, three small cell 5G network infrastructure filters including two Band n77 filters and one Band n79 filter, a 3.8 GHz filter and five S-Band filters for defense phased-array radar applications, a 3.6 GHz filter for the CBRS 5G infrastructure market and a C-Band filter for the unmanned aircraft systems (UAS) market. The Company is also developing several new filters for the sub-7 GHz bands targeting 5G mobile device, network infrastructure, WiFi CPE and defense markets.
