Resonant Inc. to Introduce New 5G RF Filter Breakthrough at the 2018 IEEE International Ultrasonics Symposium in Kobe, Japan, on October 24th

GOLETA, CA – October 8, 2018 – Resonant Inc. (NASDAQ: RESN), a leader in transforming the way radio frequency, or RF, front-ends are being designed and delivered for wireless devices, today announced its breakthrough 5G filter technology – XBAR – will be introduced for the first time at the 2018 IEEE International Ultrasonics Symposium (IUS), to be held October 22-25, 2018, in Kobe, Japan.

The new breakthrough is a fundamentally novel resonator, the building block of an RF filter. The technology is important because it is designed to offer a cost-effective filter operating at frequencies of 3GHz and higher, making it the first filter technology designed from the beginning for 5G.

“The high bandwidth 5G data services will operate at frequencies of 3.5GHz – 6GHz and higher, but today’s best filter technologies have limitations operating at these frequencies,” said George B. Holmes, CEO of Resonant. “The early results from our XBAR initiative are very promising and we are working hard to provide a cost-effective, high-performance option for 5G services.”

Using its ISN technology, Resonant has developed this new structure, which in simulations outperforms best-in-class FBAR resonators. The company filed patent applications on the technology earlier this year.

More details of the technology will be made available at IUS and in a press release that will be issued on October 23, 2018.

In addition, Dr. Victor Plessky, Resonant Director of Engineering at GVR, a wholly owned subsidiary of Resonant, and Dr. Julius Koskela, an acoustics tools consultant, have been invited to present at the IUS a paper titled “Hierarchical Cascading in FEM Simulations of SAW Devices,” which describes some of the fundamental technology used in ISN. The presentation will take place on October 24, 2018, at 11:00 a.m. Japan Standard Time.

About Resonant’s ISN® Technology

Resonant can create designs for difficult bands, modules and other complex RF Front End requirements that we believe have the potential to be manufactured for half the cost and developed in half the time of traditional approaches. ISN is a suite of proprietary mathematical methods, software design tools and network synthesis techniques that enable us to explore a much larger set of possible design solutions that regularly incorporate our proprietary technology. We then quickly deliver design simulations to our customers, which they manufacture or have manufactured by one of our foundry partners. These improved solutions still use Surface Acoustic Wave (SAW) or Temperature Compensated Surface Acoustic Wave (TC-SAW) manufacturing methods and perform as well as those using higher cost manufacturing methods such as Bulk Acoustic Wave (BAW). Resonant’s method delivers excellent predictability, enabling achievement of the desired product performance in roughly half as many turns through the fab. In addition, because Resonant’s models are fundamental, integration with its foundry and fab customers is seamless because its models speak the “fab language” of basic material properties and dimensions.
