About Resonant's XBAR®Filter Technology

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 3GHz and adapted to filter higher frequency bands,which has presented significant performance and capability challenges. Using WaveX™,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.

XBAR®is the first and only RF filter solution 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.

Resonant continues to protect XBAR®technology through the fundamental patents and trade secrets associated with a disruptive technology,in addition to the intellectual property associated with know-how and expertise developed subsequently.

About Resonant's WaveX™ Design Technology

Resonant creates designs for difficult RF frequency bands and modules that meet challenging and complex 5G,Wi-Fi and UWB RF front-end requirements. Using WaveX™,Resonant's designs have the potential to be developed in half the time and manufactured at a lower cost than traditional approaches. WaveX™ is a suite of proprietary algorithms,software design tools and network synthesis techniques that enables Resonant to explore a much larger set of possible design solutions.

Resonant delivers rapid design simulations to its customers,which they manufacture in their captive fabs or have manufactured by one of Resonant's foundry partners. These improved solutions still use Surface Acoustic Wave (SAW) or Temperature Compensated Surface Acoustic Wave (TC-SAW) technologies with the performance of higher cost manufacturing methods like Bulk Acoustic Wave (BAW).

Resonant's WaveX™ delivers excellent predictability,enabling achievement of the desired product performance in roughly half as many turns through the fab. In addition,Resonant's simulations model fundamental material and structure properties,which makes integration with foundry and fab customers much more intuitive,because they speak the "fab language" of basic material properties and dimensions.
