Analog Devices' New Integrated Converter Solutions Reduce Design Costs for Next-generation Wireless Infrastructures.

Easing the design challenge and costs associated with building 2.5G and 3G wireless architectures, Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, today introduced three new innovative converter-based solutions for wireless applications. Optimized for flexibility and performance, these solutions enable wireless infrastructure manufacturers to reduce overall part count and costs, and provide a foundation for software radios in multi-carrier and third generation wireless applications.

The three devices - the AD6635, AD6652 and AD9786 - can be used within a base station to reduce cost, size, and complexity. The AD6635 is the industry's first 8-channel receive signal processor (RSP). The AD6652 is an integrated radio receiver with embedded dual analog to digital converters (ADCs) and RSPs. The AD9876 is a 16-bit, 400 MSPS digital to analog converter (DAC) that achieves excellent noise and intermodulation distortion performance and provides greater levels of performance for transmit architectures. "As communications companies strive to meet demands for next-generation wireless services while maintaining a healthy balance sheet, Analog Devices responds with ground-breaking, cost-efficient solutions with unsurpassed performance," said Dave Robertson, Product Line Director for Communications Products, Analog Devices. "We continue to meet customer demands by evolving our product families to drive innovation for the wireless infrastructure market."

The AD6635 and the AD6652 are the latest additions to Analog Devices' VersaCOMM(R) family of receiver signal processors (RSPs) which down convert IF (intermediate frequency) data and present it to the digital signal processor (DSP) in a multi-carrier transceiver. In IF sampling applications, the RSP is a numeric preprocessor for the DSP, intended to replace a local oscillator, quadrature mixer, channel select filter, and data decimation in a traditional super heterodyne radio. The RSP replaces the analog mixing, filtering, and tuning functions with programmable digital equivalents, thus enhancing performance and reducing component cost. The AD6635 and AD6652 can also be used in combination with Analog Devices' SoftCell(TM) multi-mode and multi-carrier transceiver chipset.

The AD6635 RSP is capable of processing up to four wideband code-division multiple access (cdma2000 or W-CDMA) channels or eight narrowband (GSM/EDGE) carriers. It features four reconfigurable 80 MSPS wideband input RSP channels, as well as eight independent RSP channels, in a single package. Its highly flexible design allows it to share channel resources, so that it can perform both narrowband filtering and wideband processing. The AD6635 is available in a 324-ball grid array package and is priced at $37.40 per unit in 1,000-piece quantities. For more information, please visit:

The AD6652 is a highly integrated mixed-signal IF to baseband receiver that reduces printed circuit board (PCB) space and enhances signal integrity by directly coupling outputs from the dual 12-bit ADC to an on-board quad-channel, multi-mode digital RSP. Combining the ADC and RSP functions into a single chip results in easier testability, enhanced reliability, and cost savings, as compared with purchasing separate components. Optimized for use in single carrier and diversity radio architectures, it features four reconfigurable RSP channels, which can be customized for specific air standards such as processing two W-CDMA carriers. The AD6652 is available in a 256-ball grid array package and is priced at $38.25 per unit in 1,000-piece quantities. For more information, please visit:

The AD9786 is an addition to Analog Devices' TxDAC+(R) line of transmit-quality DACs. It is a 16-bit, 400-MSPS complementary metal oxide semiconductor (CMOS) DAC that sets new benchmarks in distortion and noise performance, allowing synthesis of multicarrier transmit signals at intermediate frequencies of 140 MHz and beyond. This record performance enables systems designers to eliminate an up-conversion stage and reduce overall parts count, ultimately lowering total system cost. Its 2x/4x/8x selectable interpolation filter eases data rate and output signal reconstruction filter requirements. The AD9786 is sampling in an 80-lead thermally enhanced TQFP, priced at $46.71 per unit in 1000-piece quantities. For more information, please visit:
