MACOM unveils upstream and downstream DOCSIS 3.1-compliant CATV amplifiers

M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for, RF, microwave, millimeter-wave and photonic applications) has launched a portfolio of high-performance cable TV (CATV) amplifiers designed for compliance with the DOCSIS 3.1 standard for high-bandwidth data transfer over existing hybrid fiber-coaxial (HFC) infrastructure.

Covering both upstream and downstream bands and complementing MACOM's recently introduced portfolio of DOCSIS 3.1-compliant passives, the new amplifiers are suited to head-end, node, system and line access equipment requiring broader bandwidth, high output power and low distortion. The new active components are available in integrated multi-stage and single-stage configurations, allowing system designers the flexibility to achieve the desired performance, says the firm. MACOM's offerings span a range of compact, industry-standard packaging options supporting thermal management attributes that ensure high reliability.

The new upstream single-ended, push-pull and variable gain amplifiers (VGAs) support frequency splits up to 300MHz, offering what is claimed to be excellent linearity, modulation error ratio (MER), low noise figure and high gain. The new downstream, single-ended, push-pull and variable gain amplifiers cover the extended 45-1225MHz frequency range with a variety of gain and output power levels while delivering high linearity, output power and small-signal performance.

"With this new portfolio of DOCSIS 3.1-compliant amplifiers, MACOM is enabling network equipment designers to meet DOCSIS 3.1 specifications in both the up- and downstream bands," says Graham Board, director carrier networks at MACOM. "MACOM's comprehensive offering of single-ended and push-pull upstream and downstream amplifiers coupled with our extensive portfolio of passives and filters helps to deliver superior end-to-end RF amplifier performance in HFC access amplifiers," he claims.
