Analog Devices has acquired fabless device maker OneTree Microdevices, based in Santa Rosa, California, a specialist in GaAs and GaN amplifiers for fibre-to-the-home networks, cable (CATV) networks, digital video distribution and gigabit bandwidth broadband.

ADI notes that OneTree’s portfolio, “offers best-in-class linearity, output power and efficiency... ADI now supports the complete signal chain for next-generation cable access networks.”

“Analog Devices, in combination with OneTree Microdevices, is uniquely positioned to solve the bandwidth and power efficiency challenges facing cable operators today in their efforts to increase broadband internet services for homes and businesses,” said Greg Henderson, vice president, RF and Microwave Business, Analog Devices. “OneTree’s expertise aligns with ADI’s strategic focus on GaN technology and extends ADI’s broad portfolio of high performance, RF and microwave signal chain solutions for infrastructure, defense and instrumentation markets.”

Today’s cable operators. ADI notes, are counting on next generation architectures such as DOCSIS 3.1 (Data Over Cable Service Interface Specification) and Remote PHY to increase the capacity of cable networks.
