The French-American company has developed and patented RF front end technology for mobile communications devices, such as power amplifiers and antenna switches, that uses standard CMOS processing. According to Acco, its bulk CMOS cellular power amplifier offers highly linear performance while operating at high power without breakdown or degradation. This, it adds, was previously considered impossible.
“Acco’s high-breakdown voltage CMOS transistor has broken the code on size and power efficiency in 4G power amplifiers,” says Acco chairman Rich Redelfs. “With this new round of funding, Acco now has the resources to scale and obsolete expensive GaAs power amplifiers used in today’s mobile phones.”
The funding round, led by Bpifrance, is timed to support the launch of Acco’s latest industry standard RF front end CMOS solutions and to provide R&D funds for next generation products.
