Akoustis Introduces BAW Filter Solution for China's 5G Small Cell Network Market

Akoustis Technologies has introduced its first 5G small cell base station XBAW filter solution. The company also announced the shipment of first samples to China for evaluation by a new tier-1 customer - a multi-billion-dollar global leader in telecommunications and information technology. 

The new XBAW filter (A10149) is designed specifically for the challenging filtering needs for band n79 in the emerging 5G small cell network infrastructure deployed across China. 

Akoustis’ new 5G network infrastructure filter leverages its patented and proprietary XBAW technology to deliver high frequency, high power and high performance operating in band n79 spectrum currently being deployed in 5G networks. With a smaller size, low insertion loss and high out-of-band rejection, BAW filters are expected to compete favorably against existing network infrastructure filter technologies including mono-block dielectric resonator (DR), 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 +30dBm
  • Ultra-small form factor 2.5 x 2.0 x 0.9 mm 
  • Performance over -40C to +85C
  • RoHS compliant, Pb-free package

The new 5G network infrastructure filter solution is designed and manufactured using the Company’s patented and proprietary 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 the first tandem 5.2 GHz and 5.6 GHz WiFi filters, 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, 5G network infrastructure, WiFi CPE and defense markets.
