Akoustis Expands Commercial Product Portfolio With New 3.8 GHz BAW RF Filter

  • Company’s second product manufactured using its high frequency XB1 Single Crystal BAW process -
  • High frequency solution aligns with emerging 5G frequency spectrum
  • Company expects product qualification and release in calendar Q3 2018

Charlotte, NC (GLOBE NEWSWIRE) -- Akoustis Technologies, Inc. (NASDAQ: AKTS) (“Akoustis” or the “Company”), a manufacturer of patented single-crystal bulk acoustic wave (BAW) high-band RF filters for mobile and other wireless applications, announced today the Company introduced a new high frequency BAW RF filter product at 3.8 GHz, the AKF-1938, initially targeting radar applications.

The AKF-1938 is the result of a key customer collaboration with a well-established OEM specializing in non-mobile communication systems with annual revenue of more than $1 billion. Akoustis expects to offer pre-production packaged product samples later this quarter.

The AKF-1938 is a high performance, ultra-small passband 3.8 GHz BAW RF filter designed for use in radar and RF transceiver applications. The filter wafers will be manufactured using Akoustis’ new proprietary XB1 single-crystal BAW manufacturing process, which delivers high-performance RF filter solutions for frequencies up to 7 GHz. The AKF-1938 provides low insertion loss covering 100 MHz of bandwidth and meets the stringent rejection requirements for microwave radar applications. The filter solution incorporates standard commercial module packaging and is compatible with high-volume, lead-free SMT soldering processes. The product is expected to be fully qualified for high volume manufacturing in the third quarter of calendar 2018.

The AKF-1938 filter features:

  • High frequency operation at 3.8 GHz
  • Wide bandwidth covering 100 MHz
  • Low insertion loss in filter passband
  • High rejection with >40 dB over wide spectrum up to 10 GHz
  • Single-ended 50 Ohm input/output ports
  • Ultra-small form factor packaged module at 2mm x 2.5mm x 0.9mm
  • High operating temperature range from -40 C to +105 C

Jeff Shealy, Founder & CEO of Akoustis, said, “The AKF-1938 is our second RF filter product announcement in the sub-6GHz spectrum and operates in the recently allocated spectrum for 5G mobile. The product supports a key radar customer engagement which we expect to transition to production later in 2018 and will be added to our product catalog for other wireless applications.” Mr. Shealy continued, “Operating at 3.8 GHz, this filter further demonstrates the capability of our patented single crystal BAW technology to reach frequencies currently lacking high performance BAW solutions.”

The Company’s XBAW single-crystal BAW manufacturing process supports a wide range of frequency spectrum up to 7 GHz, covering 2 GHz and 5 GHz WiFi, 4G LTE and emerging 5G cellular and C-V2X applications. In March, the Company announced its first commercial filter product on its proprietary XB1 process, creating the industry’s first commercial 5.2 GHz BAW filter designed for use in tri-band WiFi router applications.

Dave Aichele, VP of Business Development, stated, “The AKF-1938 addresses a key customer requirement providing high performance and significant reduction in size critical for multi-element phased array radar applications.” Mr. Aichele continued, “The product offers low loss at 3.8 GHz, high temperature operation up to +105 C, along with high rejection across a broad spectrum up to and above 10 GHz.”

The AKF-1938 will support demanding temperature operation and high rejection performance requirements. The product offers low insertion loss in a small form factor enabling compact phased-array radar systems. Companies that are interested in evaluating the AKF-1938 should contact Akoustis at

About Akoustis Technologies, Inc.
Akoustis® ( is a high-tech BAW RF filter solutions company that is pioneering next-generation materials science to address the market requirements for improved RF filters - targeting higher bandwidth, higher operating frequencies and higher output power compared to incumbent polycrystalline BAW technology deployed today. The Company utilizes its proprietary XBAW single-crystal BAW manufacturing process to produce bulk acoustic wave RF filters for mobile and other wireless markets, which facilitate signal acquisition and accelerate band performance between the antenna and digital back end. Superior performance is driven by the significant advances of high-purity, single crystal piezoelectric materials and the resonator-filter process technology which drives electro-mechanical coupling and translates to wide filter bandwidth.

The Company plans to service the fast growing multi-billion-dollar market of device OEMs, network providers, and consumers to diminish front end phone heat, battery drain and signal loss -- all considered to be directly related to current RF polycrystalline filter technologies' limitations. The Company owns and operates a 120,000 sq. ft. ISO-9001 certified commercial wafer-manufacturing facility located in Canandaigua, NY, which includes a class 100 / class 1000 cleanroom facility - tooled for 150-mm diameter wafers - for the design, development, fabrication and packaging of RF filters, MEMS and other semiconductor devices. Akoustis Technologies, Inc. is headquartered in the Piedmont technology corridor near Charlotte, North Carolina.
