Resonant

Resonant is a development-stage company that creates radio frequency (RF) filter solutions for mobile devices and wireless applications. The company operates on a fabless business model, focusing on intellectual property, software, and a services platform to design filters for the RF front-ends of mobile devices. Its primary revenue comes from licensing its proprietary design platforms and extensive IP portfolio to manufacturers and fabless companies.

Founded in 2012 by Neal Fenzi and Robert Hammond, the company was established to transform the RF front-end market. A significant milestone was its acquisition by Murata Manufacturing, a global leader in electronic components, which was announced in February 2022 for approximately $295-$300 million and completed in March 2022. This acquisition integrated Resonant as a wholly-owned subsidiary, combining Murata's manufacturing capabilities with Resonant's design technology.

Resonant's core technologies are its design software platform and its XBAR resonator technology. The company's proprietary design platform, which has evolved from Infinite Synthesized Networks (ISN) to the newer WaveX, uses a suite of software tools and simulation capabilities to create complex RF filter designs with greater efficiency and reduced time-to-market. This platform enables the design of Surface Acoustic Wave (SAW) and Bulk Acoustic Wave (BAW) filters. The XBAR technology is a BAW resonator designed specifically for the high-frequency and wide-bandwidth requirements of 5G, Wi-Fi 6/6e, and UWB networks. It offers superior performance in terms of insertion loss, rejection levels, and power handling compared to traditional filter technologies, particularly at frequencies above 3 GHz. Resonant holds a robust patent portfolio, with over 300 patents issued or pending, a significant portion of which are dedicated to the XBAR technology.
