TriQuint Semiconductor Inc., a leading RF solutions supplier and technology innovator, announced several new premium filters for next-generation smartphones and other mobile devices. The high-performance filters utilize the company’s advanced acoustic wave filtering technologies to address some of the industry’s toughest LTE interference problems.

The number of cellular and Wi-Fi bands packed inside compact high-end smartphones is skyrocketing to support 2G/3G/4G voice and data services, as well as global roaming. Advanced filter technology is required to mitigate the resulting interference issues. A global spectrum crunch adds to the growing interference problems as governments around the world squeeze new 4G bands with higher performance requirements next to existing bands, often with minimal band guards.

“TriQuint’s expanding line of advanced filters solves challenging LTE interference issues for mobile device manufacturers and can provide higher data rates over longer distances for end-users,” said Sean Riley, Vice President of Mobile Products. “Our specialty quadplexer also enables carrier aggregation techniques for operators eager to boost spectrum efficiency within their overburdened networks. These filters leverage our proprietary acoustic wave technologies to accelerate the next generation of wireless communications.”

TriQuint’s specialty filters are capturing numerous design wins in high-volume 4G smartphones from multiple manufacturers, as well as coveted sockets on reference designs from leading chipset suppliers. The new filters reflect the TriQuint hallmark:  providing industry-leading performance in the world’s smallest form factors. They include the industry’s first diplexer for LTE Bands 38 and 40, which is more than 30% smaller than discrete solutions. TriQuint also unveiled the first carrier aggregation module for Bands 2/25 and 4, an integrated quadplexer that is half the size of discrete architectures. The company’s new Band 7 LTE duplexer and its Band 41 LTE receive filter both achieve exceptionally low insertion loss to help maximize the incoming signal strength, resulting in higher data throughput over longer operating distances.
