BOSTON -- At the WiMAX World Conference, Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, is demonstrating the first two devices in a family of RF (radiofrequency) transceivers for WiMAX (Worldwide Interoperability for Microwave Access) certified terminals that will help lower the cost and drive the wide-scale deployment of broadband wireless access.Based on the 802.16 standard, WiMAX terminals provide wireless broadband connectivity and are low cost alternatives to wired solutions such as DSL and cable modems. Leveraging ADI's data conversion and RF signal processing expertise, the new transceivers integrate high-performance data converters on chip and deliver outstanding RF performance, enabling a WiMAX terminal solution that meets the reduced cost requirements essential for high volume deployment. Excellent RF performance ensures expanded coverage and improved service quality--factors that enhance the user experience and help to facilitate consumer adoption.

Unlike conventional solutions that implement the analog functions on separate devices or include the data converters on the ASIC, theAD9352 and AD9353 RF transceivers utilize "smart-partitioning," a concept pioneered by ADI, to integrate all the analog signal processing technology--analog-to-digital converters (ADCs), digital-to-analog converters (DACs), and RF functions--on a single chip. This allows the digital baseband chips to be manufactured on more cost-effective fine line processes, such as 90 nm or 65 nm. The transceivers feature a direct connection to the digital modem via theADI/Q(TM) digital I/Q interface, a simple parallel CMOS digital I/O interface that has been adopted by multiple digital modem partners.

"ADI is the first company to introduce RF CMOS direct conversion WiMAX transceivers that combine high integration with high performance, and offer the ADI/Q digital I/Q interface for a seamless connection to the digital baseband," said Bernard Aboussouan, VP, marketing and business development for Sequans Communications, a leading supplier of fixed and mobile WiMAX silicon and software. "We chose to partner with ADI and implement the ADI/Q digital interface on our SQN1110 802.16e compliant digital baseband. We are confident that ADI's WiMAX transceivers combined with our digital baseband will offer a solution that meets the price, performance and time-to-market requirements of WiMAX terminal manufacturers."
