Ultra small form factor 2mm x 2.5mm x 0.9mm Single ended Tx/Rx ports High rejection enables co-existence with adjacent WiFi UNII bands High power rating, maximum +30dBm Low insertion loss passband filter Performance over -40C to +85C RoHS compliant, Pb-free package Bulk acoustic wave (BAW) high-band RF filters developer, Akoustis, has announced the shipment of its AKF-1252 XBAW filters to a multi-billion-dollar Tier 1 WiFi OEM. The WiFi OEM requested 5.2 GHz RF filters to evaluate for inclusion in their new 802.11ax tri-band MU-MIMO customer premise equipment (CPE). Upon successful evaluation, Akoustis expects a design win and production ramp to begin as early as Q2 of CY19.The AKF-1252 was chosen due to its high performance and significantly smaller size relative to incumbent dielectric resonator (DR) filters. It is the only high performance, coexistence 5.2 GHz BAW filter commercially available today, providing the smallest form factor, which offers up to 23x size reduction compared to DR filters currently used in WiFi systems.Akoustis’ AKF-1252 is a high performance, ultra-small band-pass 5.2 GHz BAW RF filter designed for use in tri-band WiFi router applications. The filters are produced using Akoustis’ proprietary XBAW manufacturing process, which delivers high-performance RF filter solutions for frequencies up to 7 GHz to address critical RF filter requirements for existing and next generation communications applications, including the emerging 5G mobile network. It provides low insertion loss covering U-NII-1 and U-NII-2A bands and meets the stringent rejection requirements enabling coexistence with U-NII-2C and U-NII-3 bands. The industry-leading high-power rating satisfies the demanding requirements of the latest WiFi standards including 802.11ax. The filter solution incorporates standard commercial module packaging and is compatible with high-volume, lead-free SMT soldering processes.Akoustis completed final engineering modifications to the AKF-1252 design in August and has since received pre-production orders from a multi-billion-dollar Tier-1 SoC vendor as well as a distributor partner, both of which are expected to ship in the current quarter. Separately, the company has shipped evaluation boards and individual AKF-1252 filters to more than a dozen potential customers.Highlights of the AKF-1252 Filter: Click here to learn about the Akoustis AKF-1252.
