TriQuint's High-Performance Filters Capture 4G Smartphone Design Wins in Fast-Growing Market

Advanced acoustic wave technology delivers superior filter performance for multiband smartphones

HILLSBORO, Ore.--(BUSINESS WIRE)-- TriQuint Semiconductor, Inc. (NAS: TQNT) , a leading RF solutions supplier and technology innovator, has gained design wins for its new high-performance acoustic wave filters in sought-after 4G smartphones from manufacturers including Samsung, LG, HTC and Motorola Mobility. Now shipping in volume, the new filters leverage the company's broad technology portfolio to deliver the superior filter performance required for the most challenging LTE frequency bands.

LTE deployments are driving demand for high-performance filters in today's multiband smartphones. High-end smartphones house a growing number of cellular and Wi-Fi bands to support 2G/3G/4G voice and data services, as well as global roaming. In addition, the global spectrum crunch is leading governments around the world to squeeze new bands for 4G wireless services next to pre-existing bands, often with minimal guard bands. Advanced filter technology is needed to mitigate the resulting interference issues.

"Our customers count on TriQuint to solve their toughest filtering challenges," said Tim Dunn, Vice President of Mobile Devices. "We've achieved significant advancements in acoustic wave technology, thanks to three decades of filter innovation and our extensive manufacturing expertise. We're one of the very few high-volume suppliers that can meet the demanding performance requirements for the most stringent LTE filter bands. In the years ahead, deployments of next-generation LTE Advanced will spur even more demand for TriQuint's high-performance filters to reap the benefits of carrier aggregation."

Filters, duplexers and switches already account for nearly half of the total $6.4 billion RF market*. As LTE networks continue to deploy, passive content in smartphones, tablets and other mobile devices will continue to grow. "TriQuint is well positioned to win more business in this important market segment — with our technology leadership, unmatched integration expertise, chipset reference designs and continuing investments in capacity," Dunn stated. TriQuint increased manufacturing capacity by 40 percent in 2011 to support customer demand for its growing mobile device portfolio.

Exploding Demand for Smartphone Filters

"The market for RF duplexers alone will reach $2.5 billion in 2016," said Yoshiyasu Andoh, president of market research firm Navian. "The wide use of WCDMA and increasing number of LTE bands is driving demand for duplexers at a significant rate. As RF complexity increases, we expect to see further integration of passives components such as filters and duplexers with active components like power amplifiers and switches."

High-Performance 4G Filtering

The demand for high-performance filters is exploding as LTE networks deploy and Wi-Fi becomes ubiquitous. New 4G frequency bands are usually assigned next to pre-existing bands for Wi-Fi and Bluetooth services, often with minimal guard bands. TriQuint's bulk acoustic wave (BAW) and temperature-compensated (TC-SAW) technologies are instrumental in enabling simultaneous voice and data for 4G smartphones that operate on many different frequency bands, often in multiple regions of the world. Since 2006, TriQuint has shipped more than 2 billion SAW filters and nearly 1 billion BAW filters.*

Besides mobile devices, TriQuint innovations in SAW, TC-SAW and BAW devices have become the bedrock of the world's most advanced radar and communications systems, through R&D with partners like the Defense Advanced Research Projects Agency (DARPA). TriQuint is the only high-volume RF supplier that offers all three filter technologies, either as stand-alone devices or integrated modules. By combining active and passive components into tiny modules, TriQuint uses innovations like CuFlip™ and its new wafer level packaging (WLP) process to deliver size, cost and performance advantages.

TC-SAW and BAW: Enabling 4G Smartphones

SAW filters arewell suited for most frequencies up through 1.9 GHz, such as standard GSM, CDMA, and 3G bands. Some new 3G and 4G WCDMA duplexers and filters are best served by TC-SAW, which reduces temperature drift for more challenging specifications. For example, TriQuint uses TC-SAW to support Band 13, Band 20 and Band 26 duplexers.

BAW is ideal for many of the new LTE bands above 1.9 GHz, delivering superior performance with lower insertion loss, steeper slopes and excellent rejection. BAW excels in applications where the uplink and downlink separation is minimal and when attenuation is required in tightly-packed adjacent bands. TriQuint harnesses the advantages of BAW technology to serve the following bands: Band 3, Band 7, Band 25, Band 38, Band 40 and Band 41, as well as Wi-Fi co-existence filters.
