Unity Wireless Announces its Smart Power Amplifier Project will Utilize PMC-Sierra’s PALADIN Waveform Processors to Improve Performance and Power Efficiency

9/19/2002 - Unity Wireless, a leading provider of high performance power amplifiers to the wireless industry, announced its Smart Power Amplifier Project will utilize PMC-Sierra's PALADIN waveform processors to develop digital pre-distortion power amplifiers. The Smart Power Amplifier Project, which incorporates advanced technologies and theories into a line of "Smart" power amplifiers, offers improved power amplifier solutions.

Unity's Smart Power amplifiers provide the highest levels of efficiency and performance while reducing the amplifier's size. In high power CDMA applications like those used in advanced 3G, or third generation, networks, digital pre-distortion technology promises greater performance and efficiency than more traditional power amplifier designs.

"PMC-Sierra's PALADIN devices simplify the design of wireless transmitter subsystems and enable improved power efficiencies for multi-carrier base stations," said Laurie Wallace, Director of Strategic Marketing, Wireless Products of PMC-Sierra's Service Provider Division. "Our developments with Unity Wireless further illustrate our ability to provide our customers with increased network power and cost-efficiencies."

"We are excited to work with PMC-Sierra to develop advanced digital power amplifier solutions," said Ilan Kenig, Unity Wireless Corporation's President. "PMC-Sierra's state-of-the-art PALADIN power waveform processors, which are optimized for their digital pre-distortion semiconductor solution, complement our Smart Power Amplifier Project product developments."

About PMC-Sierra's PALADIN Family of Waveform Processors
The PALADIN family of waveform processors includes the PM7819 PALADIN Waveshaper, PM7800 PALADIN 10 and PM7815 PALADIN 15 devices for next-generation 2.5 and 3G wireless networks. These devices, which are used in digital, pre-distortion power amplifier base transceiver stations, provide improved spectral power efficiencies of more than 50% over feed-forward solutions. The PALADIN 10 is suitable for up to 2-carrier W-CDMA and up to 6-carrier IS-95/CDMA2000 multi-carrier systems. The PALADIN 15 is suitable for up to 4-carrier W-CDMA/UMTS and up to 16-carrier IS-95/CDMA2000 systems. The PALADIN Waveshaper performs digital multi-carrier combining optimized for W-CDMA and CDMA2000 systems.
