DURHAM, NC – Nitronex, a company developing and making high performance radio frequency power transistors for commercial and military markets, has raised $3.68 million of $4 million sought via the sale of promissory notes and stock purchase warrants, according to a regulatory filing.

The company raised $4 million in debt financing in April. It has raised at least $46.6 million in venture-backing since its founding in 1999 from Alloy, ARCH, Intersouth Partners, Diamondhead Ventures, VantagePoint Venture Partners and Contender Capital.

The company has not yet responded to TechJournal South’s request for more information on the current raise.

Its patented technology provides significant performance and cost advantages for a number of important markets including cell phone towers, car dashboard displays, DVD lasers, military communications and other applications, the company says.

The technology is based on research at North Carolina State University.
