AUSTIN, Texas -- PulseWave RF(TM), Inc. (formerly PropheSi Technologies(TM), Inc.), a fabless semiconductor company providing modules for the wireless infrastructure market, today announced that it closed a $30 million Series C funding round led by Oak Investment Partners. Existing PulseWave RF investors, including Austin Ventures, Bay Partners and Genesis Campus, also participated in the round. PulseWave RF will use the funding to commercialize its Class M Power amplifier module, the industry's first digital power amplifier architecture for wireless base stations. In addition, the investment will support the company's expansion of its operations, sales & marketing and engineering teams.

"This investment underscores our belief in the tremendous impact that the PulseWave RF Class M Power technology will have on the wireless base station market," said Bandel Carano, Managing Partner at Oak Investment Partners. "By creating the first technology to bring wireless power amplifiers into the digital age, PulseWave RF has demonstrated a 40 percent increase in power efficiency in base stations and will drive tremendous performance improvements and cost reduction, and we look forward to working with the company's talented team in bringing this technology to the markets and its customers."

The new PulseWave RF proprietary Class M Power technology is the industry's first digital RF power amplifier architecture, delivering an unrivaled level of integration and performance. Designed to meet the challenging requirements of CDMA 2000, WCDMA, ODFMA/WiMAX and future air interfaces, the new Class M Power module will reduce the amplifier cost and form factor by 50 percent and operate at efficiencies greater than 25 percent. The net effect will be a 20 percent overall reduction in the capital cost of today's wireless base stations.

"Since successfully demonstrating our digital power amplifier prototypes in March, the world's leading telecom manufacturers have shown incredible interest in this new technology," said Graham Haddock, president and CEO of PulseWave RF.
