Resonant’s XBAR Achieves Technological Breakthrough; Industry’s First Successfully Manufactured XBAR 5G Filter for Non-Mobile, on Standard SAW Process

Next-Generation 5G Filters for Non-Mobile Applications Showcase Ability to Maximize Data Speed by Minimizing Signal Loss and Interference, All on a Simple, Cost Effective SAW Process

GOLETA, Calif., Aug. 18, 2020 (GLOBE NEWSWIRE) -- Resonant Inc. (NASDAQ: RESN), a leader in transforming the way radio frequency, or RF, front-ends are being designed and delivered for mobile handset and wireless devices, has announced that its patented 5G XBAR filters, for non-mobile applications have been successfully manufactured by two different foundry partners using a standard surface acoustic wave (SAW) front end process.

Resonant’s unique ability to manufacture a complex 5G filter on a SAW front end process was made possible by the company’s EDA multi-physics (software) platform, Infinite Synthesized Networks (ISN).

Both partners manufactured Resonant’s XBAR filter, which was designed for the non-mobile n79 5G band, which pertains to applications such as infrastructure, WiFi CPE and automotive, among others. To date, six separate foundries have now successfully manufactured Resonant’s XBAR filters. Resonant’s XBAR filters have previously been manufactured on a MEMs process line, as utilized by Resonant’s industry-leading partner Teledyne. The collaboration with Teledyne continues as we expand the capabilities of the non-mobile XBAR technology.

According to Yole Development, the processes that SAW foundries utilize are widely recognized as the cheapest, easiest, fastest and highest volume production method available for acoustic filters in today’s growing $15 billion filter market. The simplicity of the SAW manufacturing process generally experiences higher yields, cheaper material costs, less manufacturing steps, and therefore, reduced time-to-market than required by the bulk acoustic wave (BAW) filter manufacturing process, whether industry standard poly-crystalline or new single-crystalline structures.

“This technological breakthrough—which for the first time demonstrates the production of high-performance 5G filters on a standard, off the shelf SAW front end process—fundamentally validates Resonant’s ability to produce filters faster, better and cheaper,” said George B. Holmes, Chairman and Chief Executive Officer of Resonant. “Our ISN software platform has allowed us to crack the code of complex filter technology, while using only proven, high-volume manufacturing processes—as opposed to traditional BAW foundry processes which are more complex and expensive than SAW processes.”
