Akoustis Technologies, an integrated device manufacturer (IDM) of patented bulk acoustic wave (BAW) high-band RF filters for mobile and other wireless applications, announced that it has locked the process flow for its new Wafer-Level-Chip-Scale-Packaging (WLCSP). The new package is designed to support the Company’s entire XBAW® RF filter product line including filters for 5G mobile devices, 5G network infrastructure and Wi-Fi consumer premise equipment (CPE).
The first WLCSP device is expected to be technology qualified later this quarter with production release expected in the June 2021 quarter. The new package offers a significantly smaller filter footprint given its 1-to-1 ratio to the size of the filter die. The fully packaged XBAW filters using this new WLCSP have been designed, developed and will be 100% manufactured in North America.
Jeff Shealy, Founder & CEO of Akoustis, stated that this first WLCSP process flow will open up significant new markets for Akoustis as they will now be able to provide XBAW® filters to address the size requirements of 5G mobile devices – as well as provide micro-filter solutions for network infrastructure and consumer premise equipment. WLCSP is currently the most in-demand chip-scale-packaging in the mobile industry and they are thrilled to be able to offer this new technology to their growing list of customers.
Akoustis’ high frequency, high performance XBAW® process and filters are experiencing growing interest as the Company entered production in multiple markets in calendar 2020, including 5G network infrastructure, high-band Wi-Fi and phased-array radar applications.
Akoustis has added 15 filters to its product catalog including a 5.6 GHz Wi-Fi filter, a 5.2 GHz Wi-Fi filter, a 5.5 GHz WiFi-6E filter, a 6.5 GHz Wi-Fi 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, Wi-Fi CPE and defense markets.
