Akoustis Technologies has shipped first pre-production 5.6 GHz XBAW coexistence filters to a tier-1 Wi-Fi OEM. According to the company, this shipment is the first delivery of a commercial tandem 5 GHz Wi-Fi BAW filter.
Previously, Akoustis’ customer tested samples of the 5.2 and 5.6 GHz XBAW tandem filters, evaluating them for use in tri-band, MU-MIMO Wi-Fi consumer premise equipment (CPE) designs. If Akoustis wins the design, XBAR filter production will launch in 2020.
The filter is manufactured using Akoustis’ patented XBAW process in the firm’s Si-MEMS wafer fab in Canandaigua, New York.
5.6 GHz XBAW Filter Features
The tandem 5.2 and 5.6 GHz coexistence filters have smaller size and better performance than the incumbent dielectric resonator filters used in nearly all tri-band WiFi CPEs, according to Akoustis. The key parameters of the filters include:
- Frequency coverage of the entire 345 MHz UNII 2C+3 passband.
- Low insertion loss in the passband.
- High rejection, enabling co-existence with adjacent Wi-Fi UNII bands.
- +30 dBm power handling.
- Single ended Tx/Rx ports.
- Operating temperature range from −40°C to +85°C.
- 2.5 mm x 2 mm x 0.9 mm size.
- RoHS compliant, Pb-free package.
“With the recent design lock of our 5.6 GHz Wi-Fi filter, we are now focused on converting our existing Wi-Fi OEM, ODM and RFFE filter sampling into pre-production orders and manufacturing design wins. We have an opportunity to penetrate high volume Wi-Fi filter markets, with the goal of delivering significant revenue growth over the next 12 months.” — Jeff Shealy, founder and CEO of Akoustis
Akoustis has introduced several new filters during the past year, including
- 5.6 GHz Wi-Fi filter.
- 5.2 GHz Wi-Fi filter.
- 3.8 GHz filter for defense phased-array radar.
- 3.6 GHz filter for the CBRS infrastructure market and Band 25 downlink and uplink filters for LTE infrastructure.
Akoustis is developing new filters for the sub-7 Hz bands targeting 5G mobile device, network infrastructure, Wi-Fi CPE and defense markets.
