Akoustis™ Patented Single Crystal BAW RF Filter Technology Achieves Commercial Performance Milestone

Charlotte, N.C., Nov. 01, 2016 (GLOBE NEWSWIRE) -- Akoustis Technologies, Inc. (OTCQB: AKTS) ("Akoustis" or the "Company"), a manufacturer of innovative BulkONE™ bulk acoustic wave (BAW) high-band RF filters for mobile wireless, announced today a significant performance improvement in its patented single-crystal BAW technology, which the Company believes satisfies resonator requirements to produce commercial, high-band RF filters, including 4G/LTE, Wi-Fi, emerging 5G and other wireless applications.

 

As a result of combining the Company's second generation single-crystal piezoelectric material with improvements in resonator design and fabrication, a quality factor (Q) of 2,914 and a technology figure-of-merit (FOM) of 152 was achieved. Both milestones are approximately 40% higher than the last demonstrated performance reported by the Company on August 8, 2016. 

 

The results reported were for 72-ohm resonators operating at approximately 2.5GHz with a range of K-squared values from 5.2% to 7.1%, which were obtained from experimental devices targeting Q improvement. Such K-squared values are de-embedded, meaning that any effect of on-chip passive circuit elements present in our RF filter process is subtracted. K-squared is an important parameter that determines the bandwidth of RF filters. Higher K-squared performance enables wider bandwidth BAW RF filters.

 

Commenting on the announcement, Akoustis co-Chairman, Jerry Neal, stated, "The Akoustis team has demonstrated incredible progress in 2016, which includes the advances made in our single-crystal piezoelectric materials and delivering an 8-fold improvement in the quality factor (Q) of our resonator technology." Mr. Neal continued, "We believe the performance reported today positions the Company to transition from a development-stage R&D technology company into a pure-play, high-band BAW RF filter product company."

 

Akoustis CEO, Jeff Shealy, added, "While we are thrilled to report achieving commercial specifications for our patented high-band BAW technology, we believe our single-crystal materials approach will allow for further performance improvements beyond the milestones reported today."
