PulseWave RF Makes Available Samples of Industry's First Digital Power Amplifier Chipset Module for Wireless Base Stations; New Technology Reduces Overall Base Station Capital Costs by 20 Percent.

LAS VEGAS -- At the CTIA Wireless 2006 conference, PulseWave RF(TM), Inc. (formerly PropheSi Technologies(TM), Inc.) today announced limited prototype sample availability of its digital multi-carrier power amplifier (MCPA) module. The new PulseWave RF proprietary Class M Power technology provides an unparalleled level of performance and integration, and is the wireless infrastructure industry's first digital amplifier architecture. PulseWave RF will conduct private demonstrations of the Class M Power module at the CTIA Wireless conference.

"The PulseWave RF digital power amplifier module is very impressive technology," said Ian Galton, professor at the University of California, San Diego. "Using a combination of radical creativity and excellent engineering, the PulseWave RF engineers solved fundamental problems that have prevented others from achieving such outstanding performance with digital power amplifiers."

Designed to meet the air interface requirements of CDMA 2000, WCDMA, ODFMA/WiMAX, and future standards, the new Class M Power module will reduce the amplifier cost and form factor by 50 percent and operate at 25 percent efficiency. The net effect will be a 20 percent overall reduction in the capital cost of the base station. In addition to these performance improvements, the digital architecture sets new industry benchmarks for size by integrating the amplifier digitization, up-conversion, linearization and amplification functionality into a single, self-contained module that's a mere 2 1/4" x 2 3/4" (60 mm x 70 mm) in size. The initial Class M Power offering is rated at 100 Watts of peak power and 20 watts of average power. The architecture can also scale from 5 Watts to 160 Watts of linearized average power.

"In recent years, wireless base station manufacturers have been severely challenged by the need to increase the performance and reduce the cost of their analog RF amplifier solutions," said Graham Haddock, president and CEO of PulseWave RF. "By evolving to a digital architecture, manufacturers can simultaneously reduce the cost and size, while increasing the efficiency of their base stations. As the Class M Power technology matures, we also believe it will continue to deliver improvements across all performance dimensions."

Availability

A limited number of prototype evaluation kits of the Class M Power digital MCPA module will be available for the North American cellular band - 869-894 MHz - in Q2 2006. The first commercial version of the module will be generally available in the 800/900 MHz frequency range (including WCDMA) in 2007.
