Resonant Inc., a provider of RF filter products developed on a robust intellectual property platform, designed to connect People and Things, has expanded its multi-year commercial partnership with Murata Manufacturing Co., Ltd., the world’s largest RF filter manufacturer, for the development of 5G XBAR® RF filters. The expanded agreement targets RF filter designs utilizing Resonant’s proprietary XBAR® technology across additional bands.

“Extending our agreement with Murata is a tremendous validation of our partnership and XBAR® technology as we continue working together to build a high-volume manufacturing platform,” said George B. Holmes, Chairman and CEO of Resonant. “Murata continues to be an excellent strategic partner to leverage our XBAR® technology, specifically developed to meet the exacting demands of the wide bandwidth, high frequency RF market required by next generation wireless networks. This agreement brings us one step closer towards XBAR® technology reaching the market with dominant scale and solving many of the challenges next-generation networks face today.”

Resonant pioneered a novel Bulk Acoustic Wave (BAW) filter technology, XBAR®, to meet the challenging and complex RF front-end requirements of next-generation 5G, Wi-Fi and UWB networks and beyond. 4G BAW filter structures have traditionally been used at frequencies up to 3 GHz and adapted to filter higher frequency bands, which has presented significant performance and capability challenges. Using WaveX™ RF design software, Resonant evaluated various resonator, filter building blocks for wide-bandwidth, high-frequency and high-power filter designs. XBAR® was the result of these extensive studies – the optimal next-generation filter technology.

WaveX™ simulations have shown that XBAR® technology could potentially be used to develop filters for 5G New Radio (NR) devices operating in the 3 GHz to 6 GHz frequency range and also millimeter wave systems operating at 28 GHz and higher frequencies. Resonant has measured the performance of XBAR® technology up to 38 GHz.

XBAR® is the first and only RF filter technology that has natively demonstrated the performance necessary to fully realize the potential of next-generation wireless technologies, including 5G and Wi-Fi 6/6E. In addition, future wireless networks will continue to move to wider bandwidths, higher frequencies and added complexity, which will further increase the demand for XBAR® filters. Unlike traditional BAW filters which require complex, multi-step manufacturing processes. XBAR® filters are much simpler to manufacture and hence can leverage SAW foundries.
