Akoustis Technologies Inc. announced it has shipped the company’s first pre-production 5.6 GHz XBAW coexistence filters to a tier-1 Wi-Fi OEM.

This tier-1 OEM has already evaluated Akoustis’ 5.2 and 5.6 GHz XBAW tandem filter samples for inclusion in tri-band MU-MIMO designs. The OEM is targeting insertion of Akoustis XBAW filters in a new Wi-Fi consumer premise equipment (CPE) design for delivery and acceptance by the OEM’s customer. If Akoustis is awarded the design win, this CPE is expected to incorporate XBAW filters and launch into production in CY20.

The tandem 5.2 and 5.6 GHz coexistence micro-filters are ideally suited for the 5 GHz Wi-Fi bands. They offer significant size reduction and higher performance compared to the incumbent dielectric resonator filters used in nearly all tri-band WiFi CPE today. With this shipment, Akoustis is the first manufacturer to deliver a commercially available tandem 5 GHz WiFi BAW filter solution.

Jeff Shealy, founder and CEO of Akoustis stated, “With the recent design lock of our 5.6 GHz Wi-Fi filter, we are now focused on converting our existing WiFi OEM, ODM and RFFE filter sampling into pre-production orders and manufacturing design wins.”

Shealy continued, “As we now offer the world’s first tandem 5 GHz Wi-Fi BAW micro-filter solution, we have an opportunity to penetrate high-volume WiFi filter markets, with the goal of delivering significant revenue growth over the next 12 months and beyond.”

The 5.6 GHz XBAW Wi-Fi filter features:

  • Low insertion loss passband filter
  • Wide bandwidth covering entire 345 MHz UNII 2C+3 passband
  • High rejection enables co-existence with adjacent Wi-Fi UNII bands
  • Single ended Tx/Rx ports
  • High power rating, maximum +30 dBm
  • Ultra small form factor 2.5 mm x 2 mm x 0.9 mm
  • Performance over -40°C to +85°C
  • RoHS compliant, Pb-free package

The 5.6 GHz filter is designed and manufactured using the company’s patented XBAW process and manufactured in the company’s Si-MEMS Wafer Fab located in Canandaigua, N.Y.

Akoustis has introduced several new filters over the past twelve months including a 5.6 GHz Wi-Fi filter, a 5.2 GHz Wi-Fi filter, 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 device, network infrastructure, WiFi CPE and defense markets.
