Analog Devices' GSM Power Amplifier Module Achieves Full Type Approval.Business Editors/High-Tech Writers NORWOOD, Mass.--(BUSINESS WIRE)--May 5, 2004 - ADI's X-PA(TM) power amplifier family leads industry in performance. Analog Devices, Inc. (NYSE NYSE See: New York Stock Exchange : ADI), a global leader in high-performance semiconductors for signal processing applications, today announced its X-PA(TM) GSM/GPRS power amplifier module family has achieved full type approval (FTA FTA abbr. Future Teachers of America ) with several leading OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and and ODM (Original Design Manufacturer) A contract manufacturer that uses its own designs and intellectual property (IP). See contract manufacturer. GSM cellular handset manufacturers in China, Taiwan, and Korea. An important milestone in the cellular phone certification process, FTA must be complete before production shipments can begin. Today's announcement solidifies the acceptance of the X-PA family as a robust solution suitable for high-volume production. Initial production orders are now being delivered to these customers. The X-PA family is the industry's only power amplifier solution to utilize a true power control approach for superior signal integrity under all conditions. The patented technique combines a directional power coupling function with a proprietary logarithmic control IC in one module to achieve unparalleled control performance under the harshest voltage standing wave ratio In telecommunications, standing wave ratio (SWR) is the ratio of the amplitude of a partial standing wave at an antinode (maximum) to the amplitude at an adjacent node (minimum), in an electrical transmission line. (VSWR VSWR Voltage Standing Wave Ratio VSWR Vertical Standing Wave Ratio ) conditions. Directional coupling is the most widely used method for measuring transmitted output power in cell phones. In addition, Analog Devices' X-PA technology enables more accurate power control than competitive power amplifier architectures. "Analog Devices' X-PA family was first introduced in 2003," said Lew Counts, vice president of advanced linear products, Analog Devices. "Multiple customers have now designed GSM phones using our X-PA and successfully completed FTA. This is an important endorsement of the product's design features and the benefits they bring to cellular phone designers." About the X-PA Family The X-PA family is a high-power, high-efficiency GSM/GPRS mobile handset power amplifier module with integrated RF power control and measurement. The most recent member is the ADL5552, which is offered in a 6 mm x 8 mm multi-chip plastic package. By measuring and controlling the transmitted power through a directional coupler, the X-PA is setting the standard for robust VSWR and SAR (Segmentation And Reassembly) The protocol that converts data to cells for transmission over an ATM network. It is the lower part of the ATM Adaption Layer (AAL), which is responsible for the entire operation. See AAL. SAR - segmentation and reassembly (specific absorption rate Specific Absorption Rate (SAR) is a measure of the rate at which radio frequency (RF) energy is absorbed by the body when exposed to radio-frequency electromagnetic field. The most common use is in relation to cellular telephones. ) performance. The power amplifier family provides the most precise and most robust power control in the industry over a wide dynamic range. The X-PA architecture uses logarithmic detection to provide precise exponential (linear-in-dB) output power control over a range of 40 dB. The X-PA is employed in Analog Devices' SoftFone(R) GSM/GPRS platform and the recently announced Nova Wireless Engine.
