3/1/2004 - Agilent Technologies Inc. (NYSE: A) announced it is shipping samples of the industry's smallest filters to select manufacturers for integration into GSM RF front-end modules. Because of the small size and superior thermal performance of Agilent's film bulk acoustic resonators (FBARs), filters can now be incorporated into front-end modules, including transceiver modules. These high-performance FBAR products are on display at the Agilent booth here through Feb. 26.
"Our innovative Microcap packaging technology delivers miniature chip-scale FBAR filters that provide low temperature coefficient, small footprint and thinness perfectly suited for module integration," said Bryan Ingram, vice president and general manager of Agilent's Wireless Semiconductor Division. "The FBAR advantage has already resulted in more than 20 million units shipped, and now we're set to proliferate this filtering technology into RF front-end modules for the next generation of feature-rich mobile phones."
Agilent's FBAR filters use the company's Microcap bonded wafer chip-scale technology to create the industry's smallest RF filter. GSM transceiver and switch module manufacturers are attempting to reduce thickness from about 1.6 mm today to about 1.0 to 1.2 mm in the future. At 0.3 mm high, Agilent's bumped FBAR Microcap filters enable this reduction. In addition, with a temperature coefficient of -25 ppm/degree C, FBAR filters have only 60 percent the temperature sensitivity of surface acoustic wave (SAW) filters, making them a better choice for modules densely populated with heat sources such as transceivers or power amplifiers. The resulting thin, small, highly integrated modules accelerate time to market for handset manufacturers and make room for additional handset features, such as camera modules, GPS locators, and infrared and Bluetooth connectivity.
FBAR Filters vs. SAW Filters
Agilent's FBAR filters are built with the company's innovative Microcap bonded-wafer chip scale technology. This process produces the industry's smallest individually sealed filters in a bumped Microcap die. This breakthrough resonator technology is displacing ceramic dielectric filters and SAW filters. Key comparisons between FBAR filters and SAW filters include:
The new Microcap chip scale FBAR filters are shipping in prototype quantities to select module manufacturers. They are expected to ship in volume in Q3 2004.
