Resonant Inc. (NASDAQ: RESN), a developer of software tools and intellectual property and design services provider of filters for radio frequency front-ends (RFFE) that specializes in delivering solutions for difficult bands and complex requirements, today announced a significant extension to its development and licensing agreement with an existing customer, adding three new duplexers based on early development successes with previous engagements. The expansion encompasses the development and licensing of three duplexers targeting difficult bands. Resonant now has 7 products in development with this customer utilizing its patented technology and design tools. These designs will leverage Resonant's patented ISN Software Tools, which we believe can be instrumental in RFFE design for next-generation 5G devices. Resonant has published a whitepaper titled " RF Innovation and the Transition to 5G Wireless Technology" that provides more information on how its technology can be used in 5G RFFE. Upfront payments, milestone payments and royalty terms have been agreed upon, but will not be disclosed due to the confidential nature of such agreements. "As we continue to attract new customers, our current customers are demonstrating their confidence in our ability to design complex and competitive RF front-end filters by extending their agreements into new products," said Terry Lingren, CEO and Co-Founder of Resonant Inc. "Their confidence in our software tools, IP libraries and advanced design capabilities are driving our product portfolio growth and future licensing potential. "The demand for more filter designs continues to increase in this fast-growing market. Band proliferation and the urgency to boost data-rates remains a key driver for additional RF content, and, in particular additional filters for mobile phones. The difficult designs we are focused on are high-value, high-volume bands, which ultimately represent significant future licensing potential. With a total of 19 products now in development under formal development and licensing agreements, Resonant is moving closer to commercializing our innovative filter design capability and creating the potential for recurring royalty revenues," concluded Lingren.
