Through its Infinite Synthesized Networks® (ISN®) software tools platform, Resonant can create RF filter designs for difficult bands, modules, and other complex RF front-end (RFFE) requirements that have the potential to be manufactured with excellent predictability, enabling achievement of the desired product performance in fewer turns through the foundry compared to traditional approaches. ISN® is a suite of proprietary mathematical methods, software design tools, and network synthesis techniques that enables the Resonant team to explore a much larger set of possible design solutions that regularly incorporate the company’s proprietary technology. Design simulations are then quickly delivered to customers that manufacture devices or have devices manufactured by one of our foundry partners. These improved RF filters still use surface acoustic wave (SAW) or temperature-compensated surface acoustic wave (TC-SAW) manufacturing methods and perform as well as those using higher cost manufacturing methods such as bulk acoustic wave (BAW). In exploring the use of ISN® for BAW, Resonant developed a brand-new BAW resonating structure called XBAR®. XBAR® technology is ideal for emerging 5G mobile devices that need wider bandwidths at higher frequency, and XBAR filters can be manufactured using existing fabrication processes for fast production. Resonant's models are fundamental, easing integration with foundry partners because Resonant’s models speak the "foundry language" of basic material properties and dimensions.

Our ISN® platform provides the design and IP foundation for XBAR® filters targeting new 5G applications.
