Akoustis Ships Five New High-Frequency XBAW Filters to its Defense Customers

Akoustis Technologies has announced that it has completed sample development and shipped five new high-frequency S-Band XBAW filters to a defense customer for a radar defense program.

Akoustis previously completed the design and shipment of its first 3.8 GHz XBAW filter solution to its defense customers in May 2019. As that initial filter transitioned into production, in July, the customer awarded Akoustis a follow-on order for the development of five additional XBAW filters in S-Band (that is, frequencies ranging from 2 to 4 GHz) radio frequency spectrum. Upon final approval, the new filter designs will be integrated into receiver modules for multi-element, active-phased array radar (PAR) systems.

The five new S-Band XBAW filters are expected to ship commercially in the calendar 2020 and operate in frequencies that are closely aligned with sub-6 GHz bands used for 5G mobile infrastructure and handsets. With the development of five XBAW filters in S-Band, Akoustis continues to demonstrate its competence and capability in high-performance coexistence BAW micro filter solutions at high frequencies.

With this key achievement related to the defense market, Akoustis continues to execute on important corporate milestones. Developing and delivering these five S-Band XBAW filters in less than six months is a significant and coordinated achievement by their engineering and operations teams. The Company continues to explore avenues for near-term revenue opportunities for high-band, high-performance XBAW filters for the defense, WiFi, 5G infrastructure, and 5G mobile markets.

The five new S-Band radar filters are manufactured using the Company’s patented XBAW process and manufactured in the Company’s Si-MEMS Wafer Fab located in Canandaigua, NY.

The New S-Band Filters feature:
  • High-frequency operation in 2 to 4 GHz range
  • Wide bandwidth covering greater than 100 MHz
  • Low insertion loss in filter passband
  • High rejection with >30 dB
  • Single-ended input/output ports
  • Small form factor allows integration in module
  • High operating temperature range from -40 C to +105 C

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.
