Akoustis Receives Pre-Production Order for Band n79 Filters for the 5G Small Cell Market

Akoustis Technologies has announced that it has received a pre-production order through a distribution partner for its band n79 (4400 - 5000 MHz) filter solution intended for a tier-1 cellular infrastructure provider for use in 5G small cell base station network equipment. This is the first of several ultra-high band filters that they are expected to deliver to the 5G base station market over the next several quarters.

Akoustis initially sampled its new band n79 (4400 - 5000 MHz) XBAW filter solution in September to this customer - its second multi-billion-dollar tier-1 cellular infrastructure provider. The solution was specifically designed for the challenging filtering needs of band n79 in the emerging 5G small cell network infrastructure deploying across China. The customer is targeting a production launch in the first half of CY2020.

The new filter solution leverages Akoustis’ patented and proprietary XBAW technology to deliver high frequency, high power, and high performance. It offers small size, low insertion loss and high out-of-band rejection which should compete favorably against existing network infrastructure filtering technologies including ceramic and cavity filters.

Small cells are low power, short-range wireless base stations that help provide service to both indoor and outdoor settings in densely populated urban areas.  Small cells are expected to play an important role in the 5G network in highly populated areas by delivering high-speed mobile broadband, low latency and better user experience.

In a recent report, Zion Market Research estimated the global small cell 5G network market was valued at around $381 million in 2018 and is expected to reach approximately $3.5 billion by 2025, at a CAGR of approximately 37% between 2019 and 2025.

The band n79 5G XBAW network infrastructure filter (named A10149) features:
  • Low insertion loss passband filter
  • High rejection enables co-existence with adjacent 5G and WiFi UNII bands
  • High return loss
  • Single-ended Tx/Rx ports
  • High power rating, maximum +30 dBm
  • Ultra-small form factor 2.5mm x 2.0mm x 0.9mm
  • Performance over -40C to +85C
  • RoHS compliant, Pb-free package

The 5G small cell band n79 network infrastructure filters are designed and manufactured using the Company’s patented XBAW process and manufactured in the Company’s Si-MEMS Wafer Fab located in Canandaigua, NY.

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.
