Powerwave Technologies Unveils Third-Generation Digitally Pre-Distorted Amplifier Technology.NEW ORLEANS New Orleans (ôr`lēənz –lənz, ôrlēnz`), city (2006 pop. 187,525), coextensive with Orleans parish, SE La., between the Mississippi River and Lake Pontchartrain, 107 mi (172 km) by water from the river mouth; founded -- Designed for WCDMA (Wideband CDMA) A 3G high-speed digital data service provided by cellular carriers that use the TDMA or GSM technology worldwide, including AT&T (formerly Cingular) and T-Mobile in the U.S. applications, this innovative technology offers industry-leading performance in power output, efficiency and reliability Powerwave Technologies, Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :PWAV), a leading global supplier of end-to-end wireless infrastructure solutions, will demonstrate its third-generation digitally pre-distorted amplifier technology today here at CTIA (1) See CompTIA. (2) (Cellular Telecommunications & Internet Association, Washington, DC, www.ctia.org, www.wow-com.com) A membership organization founded in 1984 that is involved with regulatory and public affairs issues in the wireless industry. Wireless 2005, the industry's premier wireless conference and exposition, taking place March 14-16. Developed for next-generation WCDMA and CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. 2000 applications, this digitally pre-distorted amplifier technology provides 60W of output power for up to three WCDMA carriers while providing 35% total system efficiency in the 869 - 894 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. band. The same technology will also available for the 1900 MHz and 2100 MHz bands offering 30% system efficiency. The IDEAL Architecture(TM) based DPD DPD Department of Planning and Development DPD Dihydropyrimidine Dehydrogenase DPD Dead Peer Detection (Cisco) DPD Division of Parasitic Diseases (US CDC) DPD Dominant Wave Period DPD Drug Product Database amplifier technology includes a digital IQ input, proprietary crest-factor reduction algorithms and all the required elements for a complete amplifier solution while consuming less than 175W. This breakthrough in efficiency allows customers to deploy power amplifiers in systems that were previously impossible due to size, cost, or power dissipation issues such as distributed antenna systems, base station hotels, remote boosters, and other wireless infrastructure access solutions. "As a leader in the development of innovative technology platforms for today's wireless communications networks, our digitally pre-distorted amplifier technology continues to raise the bar, offering the latest advancements for next-generation wireless technologies," said Ronald J. Buschur, President and Chief Executive Officer, Powerwave Technologies. "Additionally, the flexibility of Powerwave's IDEAL Architecture provides OEMs with the ability to cost-effectively and efficiently implement our amplifier technology within distributed antenna systems, base station hotels, remote boosters and other wireless infrastructure access solutions." About the IDEAL Architecture The advanced Powerwave IDEAL Architecture employs advanced thermal and reactive memory compensation algorithms in DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive , in order to correct for the high efficiency, highly non-linear RF amplification stages. State-of-the art nonlinear system modeling techniques are used in the predistortion engine section of the IDEAL Architecture, which achieve very high distortion suppression levels, superior to conventional DPD architectures used in high-efficiency applications. The outstanding distortion rejection of Powerwave's IDEAL Architecture is only comparable to more costly (and much less efficient) feedforward feedforward /feed-for·ward/ (fed-for´ward) the anticipatory effect that one intermediate in a metabolic or endocrine control system exerts on another intermediate further along in the pathway; such effect may be positive or negative. amplifiers.
