RFMD, a global leader in the design and manufacture of high-performance radio frequency solutions, unveiled 11 new amplifiers of which six are gallium nitride-(GaN) based products to support the requirements of the new data over cable service interface specification (DOCSIS) 3.1.
RFMD's DOCSIS 3.1 family includes 1.2 GHz power amplifiers as both hybrids and multi-chip modules (MCMs) that use state of the art GaN HEMT process technology and offer optimal linearity and output power while providing robust reliability. The newest addition to RFMD's product portfolio for DOCSIS 3.1 includes new power doubler amplifiers, push pull amplifiers, optical receivers, a reverse path amplifier, and a family of digital step attenuators. With the addition of these new products, RFMD now offers more than 25 products tailored for DOCSIS 3.1 applications, making it the industry's broadest offering.
RFMD's downstream amplifiers operate from 40 MHz to 1.218 GHz with extremely low distortion levels and excellent input and output return loss (20 dB typical). The reverse path amplifiers work up to 300MHz with high gain and highly integrated functions. RFMD's GaN technology offers the power density required to meet high power CATV requirements. RFMD has been shipping high-volume CATV GaN-based amplifiers for the past five years.
RFMD's award-winning GaN family allows cable operators and MSOs to easily upgrade existing CATV infrastructure to meet the power amplifier requirements of the new DOCSIS 3.1 standard, increasing effective downstream data rates from 160 Megabits per second (Mb/s) to 10 Gigabits per second (Gbit/s), and upstream data rates from 120 Mb/s to
1 Gbit/s when compared to DOCSIS 3.0. Due to the high output and gain benefits derived from RFMD's GaN amplifiers, cable operators can upgrade their existing equipment within current locations, saving on both installation time and cost.
"We continue to expand our family of GaN products, providing cable operators and MSOs an easy, cost-effective upgrade path to DOCSIS 3.1 to extend the life of their existing networks," said Gorden Cook, general manager of RFMD's Power Broadband Business Unit. "RFMD remains the only company shipping GaN amplifiers for CATV in high volumes and in the device and MCM packages customers need today."
