Akoustis Ships Pre-Production 5 GHz WiFi BAW Filters to Tier-1 SoC Customer

Akoustis Technologies has shipped pre-production 5.2 GHz (AKF-1252) and 5.6 GHz (AKF-1256) BAW filters to a multi-billion dollar, tier-1 SoC customer for tri-band WiFi customer premise equipment (CPE). 

The company did not name the customer but said that it is the third SoC maker to evaluate the use of the 5.2 GHz and 5.6 GHz coexistence XBAW filters for MU-MIMO reference designs in tri-band WiFi applications. Akoustis’ 5.2 GHz and 5.6 GHz filters operate in tandem to create the first BAW coexistence solution for tri-band WiFi equipment, offering a significant size advantage over existing dielectric resonator filters with up to 23 times smaller footprint. The filters provide low insertion loss, meet the demanding coexistence rejection specifications and can be surface mounted. 

The 5.2 GHz (AKF-1252) and 5.6 GHz (AKF-1256) filters are designed and manufactured using the Company’s patented XBAW process and manufactured in the Company’s Si-MEMS Wafer Fab located in Canandaigua, NY. 

Akoustis has introduced several new filters over the past twelve months including a 5.6 GHz WiFi filter, a 5.2 GHz WiFi filter, a 4.9 GHz band n79 filter for small cell network infrastructure, a 3.8 GHz filter for defense phased-array radar applications, a 3.6 GHz filter for the CBRS infrastructure market and Band 25 downlink and uplink filters for LTE infrastructure. The Company is also developing several new filters for the sub-7 GHz bands targeting 5G mobile devices, network infrastructure, WiFi CPE and defense markets.
