LONDON PulseWave RF, a developer of digital power amplifiers for cellular basestations, formerly known as PropheSi Technologies, has closed a $30 million Series C funding round led by Oak Investment Partners.
The company said it would use the funding to commercialize its Class M Power amplifier module, and to support the company's expansion of its operations, sales & marketing and engineering teams.
Existing PulseWave RF investors, including Austin Ventures, Bay Partners and Genesis Campus, also participated in the round. Freescale Semiocnductor is also an investor.
PulseWave RF's proprietary Class M Power technology, said to be the industry's first digital RF power amplifier architecture, is claimed to reduce the amplifier cost and form factor by 50 percent and operate at efficiencies greater than 25 percent. The net effect, PulseWave RF (Austin, TX.) says, 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.
