TriQuint Semiconductor Inc. has harnessed its filter product expertise and broad technology portfolio to introduce a new high-performance duplexer bank. The new filter module serves two of the world’s most challenging RF bands for smartphones and other mobile devices.
TriQuint’s bulk acoustic wave (BAW) and temperature-compensated surface acoustic wave (TC-SAW) technologies are instrumental in enabling simultaneous voice and data for next-generation 3G / 4G smartphones, particularly in RF bands with the most demanding performance requirements. TriQuint’s new TQQ2526 duplexer bank leverages both technologies, utilizing BAW to support Band 25 and TC-SAW to serve Band 26 in the North American market. The module integrates two duplexers into a single, compact package that provides extended frequency range and requires less board space.
“TriQuint has built the most advanced portfolio of filter technologies to help our customers solve interference issues in the toughest 3G/4G smartphone bands,” said Tim Dunn, Vice President of Mobile Devices. “We’ve made significant investments in capacity and hired more engineers to deliver a growing line of high-performance filters, with more to come.”
As LTE rolls out, demand is surging for high-performance filters in multi-band smartphones. High-end smartphones house a rapidly growing number of cellular and Wi-Fi bands to support 2G / 3G / 4G voice and data services, as well as global roaming. Amid a global spectrum crunch, new 4G bands are being squeezed next to pre-existing bands, often with minimal guard bands. Advanced filter technology is needed to mitigate the resulting interference issues.
TriQuint has recorded several recent design wins for its high-performance filters in sought-after 4G smartphones from manufacturers including Blackberry, HTC, LG, Motorola Mobility and Samsung*.
Product Details
The TQQ2526 duplexer bank provides outstanding filter performance, with high isolation over the full bandwidth and very low variation over temperate ranges. The highly integrated, ultra-small 2.8x4.7x1mm module features a single antenna connection, eliminating the need for antenna switching. Its low transmit insertion loss reduces total current consumption, extending battery life and usage time. The TQQ2526 enhances receiver sensitivity and dynamic range with low Rx insertion loss and high rejection of Tx signals at the Rx ports.
The TQQ2526 is sampling now and scheduled for mass production by June.
