biz.yahoo.com Monday November 27, 5:01 am Eastern Time Press Release PMC-Sierra Enters Wireless Infrastructure Market with DSP-Controlled Power Amplifier Architecture PALADIN-10 DSP Eliminates Transmitter Distortions and Improves Spectral Efficiency in Third-Generation (3G) Wireless Networks BURNABY, British Columbia--(BUSINESS WIRE)--Nov. 27, 2000-- PMC-Sierra (Nasdaq:PMCS - news) today announced its first solution in a new family of Digital Signal Processor (DSP) based chip technologies for wireless infrastructure equipment. PMC-Sierra's PALADIN-10 chip allows for traffic over all major digital third-generation (3G) wireless standards, including W-CDMA, cdma2000 and EDGE to be transmitted through a new digitally-controlled power amplifier architecture. The PM7800 PALADIN-10 (Power Amplifier Linearizer And Distortion Inhibitor) DSP is the world's first off-the-shelf chip solution that eliminates transmitter distortions and improves spectral efficiency in Base Transceiver Stations (BTS), providing the industry with the lowest cost per watt solution. Taking advantage of its advanced feature set, existing analog amplifier designs can be transformed into multi-carrier capable, digitally-controlled wideband power amplifiers able to handle the higher data rates and increased call capacity of 3G wireless services (see figure 1). Packetized Data and Voice for 3G Systems Mobile phone usage is expected to surpass 1.7-billion subscribers in the year 2005. Increasingly, users will want new wireless services such as access to corporate Intranets, the Internet, video conferencing and shared documents containing graphics. Delivering these services will require an overhaul of the existing wireless infrastructure including the network's base station infrastructure. Third-generation wireless networks must be built with higher performance and more efficient power amplifiers able to support both voice and wideband data transmitted using packet-based protocols. New 3G Base Transceiver Station subsystems designed using the PALADIN-10 DSP chip solution can deliver increased wireless capacity through improved spectral and power efficiencies, resulting in better bandwidth utilization. This reduces system cost, size and complexity while improving the reliability of the wireless infrastructure. According to Will Strauss, president and principal analyst of Forward Concepts, ``Through its unique deployment of DSP technology, PMC-Sierra's PALADIN-10 DSP will likely be the operational heart of a new class of high-performance R.F. power amplifiers for third-generation cellular base stations. Since R.F. amplifiers are one of the most expensive components in a base station, PALADIN offers the capability of using fewer amplifiers, which promises a significant reduction in wireless infrastructure cost.'' Kevin Huscroft, acting vice-president and general manager of PMC-Sierra's Wireless Products Division and the company's chief technology officer added, ``The Internet and wireless technologies are converging to form an entirely new communications platform. Capitalizing on the opportunities will require a new architecture for an entirely new generation of equipment designed to handle wideband data that is built on a foundation of flexible and highly adaptable digital signal processing techniques. The PALADIN-10 is the first of many new PMC-Sierra products that will enable this new wireless infrastructure equipment deployment.'' Overcoming Analog Limitations Analog power amplifiers are the most expensive component in wireless network base stations. They are complex and sensitive, requiring a lengthy calibration procedure prior to deployment. Routine field maintenance is also needed to ensure transmitter compliance with communications regulations and continued operation without performance degradation due to component ageing and environmental changes. The PALADIN-10 chip and control software overcome the need for expensive and time-consuming manual amplifier calibration by automatically adapting to, and compensating for, each amplifier's unique distortion pattern. This eliminates the need for tuning and alignment during manufacturing and in the field. Predistortion Preserves Wireless Signal Integrity, Maximizes System Capacity Minimizing distortion, interference and noise are fundamental challenges faced by wireless systems designers. The PALADIN-10 chip and control software eliminate analog impairments such as wideband group delay, thermal and envelope memory dependencies, and bulk AM-AM (amplitude-amplitude modulation) and AM-PM (amplitude-phase modulation) transistor effects that cause in-channel distortion and adjacent channel interference. This enables the design of linear-response transceivers exhibiting near perfect fidelity for single and multi-carrier signals up to 10 MHz bandwidth. Such performance allows system capacity to be maximized and wideband data rates to be supported, while minimizing adjacent channel interference and achieving regulatory compliance. Enabling Advanced BTS Architectures The flexibility offered by the PALADIN-10 chip and software solution gives system designers the freedom to adopt new radio resource architectures. This clears a pathway to designing wireless base stations supporting all emerging 3G wireless standards while extending system performance to include advanced base transceiver stations features such as smart antennas, enhanced power management and ``hot swap'' redundancy architectures (see attached Technical Overview for more detailed description of PALADIN-10 architecture). Pricing, Availability and Customer Support The PM7800 PALADIN-10 is a low-power 1.4 watt CMOS device packaged in 31mm by 31mm 304-pin SBGA package. The device is priced at $320 in volume quantities, with samples available in first quarter 2001. A comprehensive support package including reference designs and applications notes will be available on PMC-Sierra's web site at pmc-sierra.com.
