PMCS (MM)

PMC-Sierra, Inc. (Nasdaq:PMCS) today announced its industry-leading PM7800 PALADIN(R) 10 and PM7815 PALADIN 15 devices have successfully demonstrated compliance to the rigorous Federal Communications Commission (FCC) 04-258 WiMAX requirements. These solutions leverage PMC-Sierra's industry-standard wireless Digital Predistortion (DPD) technology and its high frequency mixed signal design capabilities to enable products for the emerging WiMAX wireless standard. "WiMAX is part of the next wave in wireless technologies," said Dr. Robert Yung, vice president and chief technology officer at PMC-Sierra. "PMC-Sierra is uniquely positioned to leverage our extensive RF and mixed signal expertise in providing a portfolio of wireless solutions. Our ability to migrate our proven DPD solutions to the demanding WiMAX standard will enable customers to be first to market with low cost WiMAX products." PALADIN is the Only DPD Engine to Meet FCC Performance Requirements The PALADIN 10 device successfully demonstrated compliance to the rigorous FCC 04-258 WiMAX requirements. Compliance to these requirements is essential for service providers planning to deploy WiMAX equipment in the 2.5-2.7 GHz range in the United States. PMC-Sierra's PALADIN 10 DPD solution, combined with Freescale Semiconductor's latest N-channel RF Power MOSFET (the MRF6S27085H) form the heart of a linear Power Amplifier (PA) for WiMAX base stations transmitting in the 2.5-2.7 GHz frequency band. "We are impressed with the performance of PMC-Sierra's PALADIN and its ability to handle WiMAX signals and deliver positive results," said David Runton, Manager of RF Systems Engineering at Freescale. "PMC's firmware-based DPD algorithm is powerful and flexible enough to handle the challenging WiMAX requirements, while providing designers an off-the-shelf solution." DPD technology has long been accepted for CDMA2000 and WCDMA 3G cellular base stations. PMC-Sierra has been a pioneer in the commercialization of DPD, and its PALADIN products have been proven in thousands of deployed 3G base stations. However, the FCC performance requirements are much more stringent for WiMAX than for 3G. The PALADIN is the only DPD engine to meet the FCC performance requirements. Chip Set Solution for WiMAX The PALADIN 10 and PALADIN 15 devices are an integral part of PMC-Sierra's radio agnostic architecture. PMC-Sierra's architecture enables customers to develop and produce a variety of radio and baseband waveform processing solutions from an integrated and cohesive chip set solution. The chip set is architected to allow economies of scale to be realized across multiple radio products, substantially easing the cost of introduction to manufacturing. The chip set integrates digital signal processing solutions that allow high density, efficient radios, complementary with software defined radio systems, and encompassing highly efficient Doherty amplifiers and envelope tracking techniques within the framework of multi-antenna transmit and receive diversity systems. About PMC-Sierra's PALADIN Family of Products Power Amplifier Linearizer And Distortion INhibitor (PALADIN) is a family of high-speed digital waveform processors for next generation WiMAX and 3G networks. The PALADIN family enables higher-performance and higher-efficiency base transceiver stations using fewer and less expensive components. The PALADIN family implements DPD PA technology in base transceiver stations to provide spectral power efficiency improvements of more than 50 per cent compared to feedforward solutions. Through its use of low-power, low-cost digital technology, the PALADIN family provides dramatic cost savings for equipment manufacturers and their customers.
