Conexant Ships 25 Millionth Device for Digital Cellular Telephones; Conexant is Leading Provider of Power Amplifiers in CDMA Market Segment.NEWPORT BEACH Newport Beach, residential and resort city (1990 pop. 66,643), Orange co., S Calif., on Newport Bay and the Pacific Ocean; inc. 1906. It is a popular seaside resort and yachting center. Manufactures include electrical and medical equipment, computers, boats, and adhesives. , Calif.--(BUSINESS WIRE)--Jan. 11, 1999--Conexant Systems Inc. (Nasdaq:CNXT), formerly Rockwell Semiconductor Systems, Monday announced it has shipped more than 25 million digital cellular power amplifier Power amplifier The final stage in multistage amplifiers, such as audio amplifiers and radio transmitters, designed to deliver appreciable power to the load. devices, making it the industry's leading provider in the Code Division Multiple Access (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. ) Cellular and Personal Communication Systems (PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. ) handset-component market. According to Dataquest, worldwide CDMA digital handset sales are expected to reach 17.4 million for 1998. With an estimated compound annual growth rate of 43 percent, this market segment is projected to grow to 72.7 million units by 2002. More than 80 percent of today's CDMA digital cellular and PCS telephone handsets use Conexant's gallium arsenide (GaAs) power amplifiers, including models made by Lucky Goldstar, Motorola, NEC (NEC Corporation, Tokyo, www.nec.com, www.necus.com) An electronics conglomerate known in the U.S. for its monitors. In Japan, it had the lion's share of the PC market until the late 1990s (see PC 98). NEC was founded in Tokyo in 1899 as Nippon Electric Company, Ltd. , Nokia, Qualcomm, Samsung and Sony. "This quarter, Conexant is shipping in excess of 2 million power amplifiers per month -- a 150 percent increase over last year," said Deepak Mehrotra, vice president, CDMA Products. "Demand continues to accelerate for these chips, and they remain one of the most important determinants of handset size, weight, cost and power consumption. "As the pre-eminent supplier, we're working hard to innovate key technologies that are quickly enabling smaller, lighter and more power-efficient cell phone handsets." Power amplifiers are a key component in digital cellular telephones, determining the talk time for the handset. Conexant's devices are based on a 50GHz heterojunction bipolar transistor The heterojunction bipolar transistor (HBT) is an improvement of the bipolar junction transistor (BJT) that can handle signals of very high frequencies up to several hundred GHz. It is common in modern ultrafast circuits, mostly radio-frequency (RF) systems. (HBT HBT Heterojunction Bipolar Transistor HBT HyCult Biotechnology (Uden, The Netherlands) HBT Hanbury-Brown-Twiss (interferometer) HBT Herring Bone Twill HBT Heflex Bioengineering Test ) process, which enables the highly efficient power amplifiers to provide CDMA handsets with talk times 50 to 100 percent over those achieved by analog cellular telephones. The digital CDMA modulation also ensures user privacy and minimizes dropped calls. First introduced in February 1996, Conexant's family of GaAs power amplifiers target a variety of digital cellular telephone applications including Global System for Mobile Communications (communications) Global System for Mobile Communications - (GSM, originally "Groupe de travail Sp?ciale pour les services Mobiles") One of the major standards for digital cellular communications, in use in over 60 countries and serving over one billion subscribers. (GSM) phones; standard single-mode CDMA and TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). (IS-36) phones; dual-mode cellular CDMA/Advanced Mobile Phone Systems (AMPS) phones; and dual-band, triple-mode phones that operate on Cellular CDMA, PCS CDMA and AMPS networks. The devices support cellular CDMA for U.S., Korean and Japanese networks, in addition to supporting PCS CDMA for both U.S. and Korean frequency bands. Conexant Systems is the $1.2 billion company that was created when Rockwell International spun off its semiconductor systems business to shareowners in December 1998. Conexant is the world's largest independent company focused exclusively on providing semiconductor products for communications electronics. The company aligns its business into five product platforms: Personal Computing, Personal Imaging, Wireless Communications, Digital Infotainment and Network Access. With more than 30 years of experience in developing analog modem technology, the company draws upon its expertise in mixed-signal processing and communications technology to deliver integrated systems and semiconductor products for a broad range of communications applications. These products facilitate communications worldwide through wireline voice and data communications networks, cordless and cellular wireless telephony systems, and emerging cable and wireless broadband communications networks. |
