RESN Resonant Inc

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 released more details about its breakthrough resonator technology that holds the potential for a new class of high-performance RF filters for 5G devices.

The new discovery is important because resonators form the building blocks for RF filters and define much of the performance achievable in a filter. Resonant’s XBAR is a new bulk acoustic wave (BAW) structure that can be produced in silicon using standard processes. Simulated utilizing the company’s ISN platform, we believe XBAR outperforms best-in-class film bulk acoustic resonator (FBAR) devices in frequencies above 3 GHz. 5G wireless services for mobile devices are expected to operate in this higher frequency range to support high-bandwidth data applications. Today’s filter technologies (surface acoustic wave (SAW), temperature compensated SAW (TC-SAW), BAW and FBAR) have operating limitations at frequencies higher than 3 GHz.

Key performance metrics demonstrated in initial XBAR resonators:

• Extremely large coupling coefficients, greater than 500 MHz at 5 GHz
  • Essential for the design of large bandwidth 5G filters
• High Q resonances, greater than 500, as high as 31 GHz

“5G technology holds the promise of brand new consumer and business services, but the requirements for filters to support high frequency, high power and high bandwidth are quite different from those of 4G. Performance of these new services will be hampered without the right filter technology that allows mobile devices to isolate the high-frequency signals,” said Bob Hammond, Chief Technology Officer of Resonant. “With XBAR BAW resonators, we are on a path to providing an alternative filter technology that will facilitate high-performance services for mobile devices.”

Developed with Infinite Synthesized Network® Resonant developed the new resonator using its Infinite Synthesized Network® (ISN®) design technology, which today provides industry leading filter manufacturers and fabless companies with the ability to design complex filters, duplexers and quadplexers.

“Utilizing Resonant’s ISN tool’s accuracy for modeling acoustic wave structures allowed Resonant technologists to investigate alternatives to current mobile resonator structures and compare their performance,” said George Holmes, Chief Executive Officer of Resonant. “It is through the continued development of our ISN roadmap that we have been able to complete the investigation and develop and patent the XBAR technology.”

Resonant has measured the performance of XBAR resonators up to 38 GHz. The simulated performance accurately models the measured data, indicating that XBAR technology could be used to develop filters for devices used in 5G, both in the 3 to 6 GHz range as well as millimeter wave operating at 28 GHz and higher frequencies.

If successful, XBAR should provide for filter designs for 5G bands with better insertion loss, better rejection levels, higher power handling and wider passbands than currently available filters.

About Resonant’s ISN® TechnologyResonant 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.
