RFMD Expands GaN range for DOCSIS 3.1

Family includes 1.2GHz power amplifiers as both hybrids and multi-chip modules

RFMD has today unveiled 11 new amplifiers of which six are GaN-based  to support  the new data over cable service interface specification (DOCSIS) 3.1. RFMD will show its CATV components at the SCTE Cable-Tec Expo in Denver from September 22-25.

RFMD's DOCSIS 3.1 family includes 1.2GHz power amplifiers as both hybrids and multi-chip modules (MCMs) that use a high performance GaN HEMT process technology. The newest addition to  the DOCSIS 3.1 range 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.

RFMD's downstream amplifiers operate from 40MHz to 1.218GHz with low distortion levels and input and output return loss. The reverse path amplifiers work up to 300MHz with high gain and highly integrated functions. RFMD has been shipping high-volume CATV GaN-based amplifiers for the past five years.

RFMD says that its GaN family are designed to allow easy upgrade of existing CATV infrastructure to meet the power amplifier requirements of the new DOCSIS 3.1 standard, increasing effective downstream data rates from 160 Mbps to 10 Gbps, and upstream data rates from 120 Mbps to 1 Gbps.

 "RFMD remains the only company shipping GaN amplifiers for CATV in high volumes and in the device and MCM packages customers need today, and we look forward to sharing additional information about this growing family of products at the SCTE Cable-Tec Expo," said Gorden Cook, general manager of RFMD's power broadband business unit.
