The 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 3 GHz 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 3.5 GHz – 6 GHz 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 (Infinite Synthesized Networks) 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.
Resonant believes that its patented ISN technology will enable the company to design complex filter products at approximately half the unit cost and in approximately half the time of traditional approaches. A large suite of proprietary mathematical methods, software design tools and network synthesis techniques enable it to explore a much larger set of possible solutions and quickly derive the optimum solution.
