Resonant Inc. has secured four design projects to add to the company's backlog, bringing the total number of designs in work to 20 with five customers.
The first engagement extends a development and licensing agreement with an existing customer, adding three new duplexers based on early development successes with previous engagements. Resonant now has seven products in development with this customer, based on Resonant's patented technology and design tools.
Resonant also signed a new development agreement with a supplier of power amplifiers (PA) and switches for handset RF front-ends (RFFE). The agreement is for the development of Resonant's second quadplexer and is the first engagement with a company that doesn't own its own fab. The agreement will enable the customer to evaluate Resonant's design tools, IP and services to design into a third-party fab to deliver a complex quadplexer.
With both engagements, the initial payments and milestone payments have been agreed upon, but they will not be disclosed.
"Our fifth customer to sign a development agreement with us is a leading RFFE supplier and a new entrant to the filter market," said Terry Lingren, CEO and co-founder of Resonant. "This development project will be designed and manufactured in close cooperation with one of Resonant's existing foundry partners, which we believe will provide this customer with a significant competitive advantage. 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."
Resonant is seeking to capitalize on the proliferation of mobile bands, as operators aggregate spectrum to handle the demand for more and faster data pipes. Each of these frequency bands requires high performance filters. Resonant has developed a patented library of RF design tools for modeling and designing traditional FBAR, BAW or temperature compensated (TC) SAW filters. The company says their proprietary tools enable their designs to use standard, low cost SAW processes and require fewer development spins. Resonant's business model is to license their designs and receive royalties on production shipments. This approach uses customers' or third-party fabs, so Resonant avoids the cost of developing process technology and building manufacturing facilities.
