Resonant, a leader in transforming the way radio frequency, or RF, front-ends are being designed and delivered for mobile handset and wireless devices, announced that its customers have cumulatively surpassed the milestone of shipping 50 million RF filters designed with the Company’s proprietary ISN® technology.
The RF filters cover a total of 9 cellular and Wi-Fi bands across multiple customers, primarily for use in mobile handset, infrastructure, asset tracking (GPS) and automotive applications. Designed on standard topologies, such as surface acoustic wave (SAW) or temperature-compensated SAW (TC-SAW) technologies, and most recently bulk acoustic wave (BAW) using standard processes, Resonant’s customers delivered RF filters for use in various applications, including discrete chip scale packaging (CSP) for use on chip on board (COB) and wafer level packaging (WLP) for use in modules. In November, Resonant announced that its customers had shipped over 46 million RF filters to-date, and a total of 4.1 million RF filters in the third quarter of 2020 alone, representing a year-over-year increase of 163%.
Resonant’s Infinite Synthesized Networks (ISN®), multi-physics Electronic Design Automation (EDA) software platform is used specifically for designing RF filters, which they believe is making the design process for filters better, faster, and more cost effective than competing approaches. Resonant’s XBAR technology, invented using the ISN® platform, is an RF filter technology that has showcased the ability to innately meet the complex requirements for bandwidth of 5G and Wi-Fi 6 and 6e applications.
“The milestone of our customers cumulatively shipping 50 million RF filters with our technology is significant, as it further validates the effectiveness of our proprietary ISN® technology and intellectual property, while also representing the early innings of our anticipated ramp in future revenues and volumes,” said George B. Holmes, Chairman and CEO of Resonant. “This volume milestone of customer shipments with our technology is important, but even more significant is where we are seeing our technology surface in the marketplace. For instance, our oldest customer indicated that they recently secured a high-volume Wi-Fi socket with a Tier 1 Chinese handset OEM, which has already started shipping. In addition, our technology has also been identified by third-party teardown companies in multiple Tier 1 phone models.
“As we move into 2021, we expect our customers to continue their strong volume shipments, while also securing new contracts covering RF filter designs for 4G, 5G and Wi-Fi applications across a myriad of mobile and non-mobile applications.”
Radio frequency (RF) filters, such as those designed by Resonant, are components embedded into a smartphone that reject and accept the appropriate signals. As 5G continues to develop and grow in importance, so will the ways RF filters are utilized in everyday life beyond texting, calling or streaming your favorite movie on a smartphone. Soon RF filters will be sited into autonomous and electric vehicles that will help relay when your car is too close to an object, out of its traffic lane or needs to stop, where speed is critical. For example, a one-second delay in the communication link with an RF filter could equal a delayed stop of 100 feet in a vehicle traveling at approximately 70 mph. In addition, hospitals are beginning to rely on RF filters to eliminate disruptions in their hospital networks, helping minimize the risk for areas such as remote surgery via robotic medical equipment. Put simply, RF filters provide protection for the wireless connectivity to sectors such as traffic, health, weather and environmental monitoring, and allows wireless communication in the same way as computers and smartphones.
