TriQuint Semiconductor, Inc., has captured design wins with its new high-performance filters in next-generation 4G smartphones from multiple manufacturers. These devices utilize TriQuint’s advanced bulk acoustic wave (BAW) technology to solve the toughest interference problems in today’s increasingly crowded RF spectrum.

“TriQuint offers the industry’s broadest portfolio of filters based on BAW, SAW and TC-SAW technology. Our BAW filter production has increased significantly, based on multiple new smartphone design wins.”

“Today’s announcement of three new filters will be followed by more products to meet stringent 4G performance requirements around the world. As carriers roll out 4G networks, demand is surging for premium filters,” said Tim Dunn, Vice President of Mobile Devices. “TriQuint offers the industry’s broadest portfolio of filters based on BAW, SAW and TC-SAW technology. Our BAW filter production has increased significantly, based on multiple new smartphone design wins.” According to analysts, 4G connections are expected to explode to 1 billion by 2017*.

Some 4G bands are being squeezed right next to existing Wi-Fi spectrum, with little or no band guards. Mobile device manufacturers rely on TriQuint’s high-performance filters to keep RF signals in the crowded spectrum isolated from one another, thereby preventing problems such as dropped calls. TriQuint has begun shipping several new BAW filters in high-volume smartphones and continues to expand its product portfolio to address the most vexing filtering challenges.
