TriQuint's new NoDrift and LowDrift RF filter technologies target LTE coexistence challenges

RF front-end component maker and foundry services provider TriQuint Semiconductor Inc of Hillsboro, OR, USA says that its advances in filter technology are achieving what is claimed to be unmatched temperature stability. Specifically, the specialty LowDrift and NoDrift filters utilize the firm’s proprietary technology processes to tackle some of the industry’s toughest LTE interference challenges.

As more LTE frequency bands are squeezed next to existing bands worldwide to accommodate rapidly increasing mobile traffic usage, interference problems are rising significantly. Traditional filter technologies often are unable to meet the most challenging interference requirements, particularly for temperature-sensitive applications.

TriQuint says that it has developed fabrication processes that dramatically improve filter temperature stability, resulting in less service disruptions, fewer dropped calls, and improved insertion loss and mobile device battery life. As the table shows, the firm’s LowDrift technologies for surface acoustic wave and bulk acoustic wave (SAW and BAW) filters decrease temperature drift significantly, and its newest NoDrift technologies can virtually eliminate it.

“As temperature stability becomes a more critical filter performance factor, TriQuint’s NoDrift and LowDrift filter processes solve band coexistence problems which our customers are unable to address with any other technology,” says Sean Riley, TriQuint’s VP of Mobile Products. “We plan to expand our premium filter portfolio significantly in the months ahead as we continue to capitalize on the need for highly specialized filtering solutions and drive higher addressable content opportunities.”

Analysts are predicting that demand for high-performance filters will rise even further as LTE deployments accelerate worldwide. “We expect premium filter sales to continue to out-strip expectations near-term and, with less than 10% of world subscribers on LTE, peak filter demand remains years away,” comments Edward Snyder, managing director of Charter Equity Research.

TriQuint says that its premium filters are supporting more than 50 unique customers worldwide and have garnered multiple reference design wins with all major chipset providers.
