Murata Completes Acquisition of Resonant Inc.


Reading time ( words)

Murata Manufacturing Co., Ltd. is pleased to announce that the acquisition of Resonant Inc., a leading company in RF filter design, was completed on March 28, 2022 (U.S. time).

Murata Manufacturing is an established global leader in the electronics industry. The company prides itself on having built trusted relationships with customers in the capacitor and communication technology markets. As a result, Murata has significant market share for multiple electronic components, such as SAW filters for communications, which represents a 50 percent global market share.

Within telecommunications, one of Murata Manufacturing's core strategic areas, technology standards are continually updated to enable faster communication speeds, multi-device connections, and lower latency. Currently, 5G and next-generation Wi-Fi standards are being deployed worldwide. To fully leverage the high-speed communications these standards allow, devices need to accurately receive high-frequency signals. Given that, there is a growing need for high-performance, wide-bandwidth, high-frequency filters that can remove unwanted noise and allow only the necessary signals to pass through with low loss.

Signals in the high-frequency band are expected to increase significantly. To meet that anticipated demand, Resonant's proprietary XBAR technology* achieves high attenuation with low loss and steep filter characteristics, making it possible to suppress signals that existing filters have been forced to accept as noise. This technology will be critical in achieving reliable, high-speed wireless communications for standards such as 5G and beyond.

With this acquisition, Murata Manufacturing further strengthens its position as a leader in the telecommunications market by combining filter and process technologies and proprietary manufacturing capabilities with Resonant’s XBAR technology to provide advanced high-frequency filters.

Murata Manufacturing President Norio Nakajima stated the following: "As utilization of the high-frequency spectrum progresses, we expect that many frequency bands will be adjacent to each other, as is the case with those already in use. To fully realize the benefits of high-speed communication standards, reliable, precision electronic components that meet the required specifications, regardless of the communication environment, are essential. We are very pleased to be able to combine the Resonant technologies with our own to deliver leading-class solutions to our customers."

Preparing the Next-gen Tech Workforce

05/18/2022 | Marc Carter, Independent Contributor
Knowledge transfer, especially from the “graying-out” experienced technical workers in our industry, is a complex, difficult family of problems. It differs wildly between companies, and even within divisions of the same company. One of the biggest barriers is the full manufacturing schedules in North American electronics companies that don’t leave any slack time—and the 40-hour work week is a complete fantasy for many.

Are Your Existing Machines Enough to Keep Up?

05/04/2022 | Jennifer Davis, Arch Systems
Buy new or make do? It’s an age-old debate for manufacturers who are trying to decide how best to manage machine assets inside their manufacturing facilities. New machines are expensive, but so is operating existing machines at a comparative deficit.

Finding Solutions in the Quoting Process

05/03/2022 | Duane Benson, Screaming Circuits
It’s easy to frame all our supply chain woes around the COVID-19 pandemic. However, at Screaming Circuits, we started receiving dire warnings about component shortages in early 2018. At that time, we were told that the supply upheaval could last years and that we should expect it to get much worse before it got better. Now, four years later, I would say those warnings nailed it.
