CATV and broadband devices
M/A-COM Technology Solutions (MACOM), a supplier of RF, microwave, and millimetre wave products, will showcase its industry leading portfolio of CATV and broadband devices enabling the evolution of modern cable networks at ANGA COM 2014, Cologne, Germany.
To keep pace with the exponential growth in data demand while using previously deployed fibre and copper, cable networks are working toward the deployment of DOCSIS 3.1 equipment. This requires changes to the active and passive components within the infrastructure and customer premise equipment, such as higher power, linearity and bandwidth amplifiers, improved rejection filters, and a full new suite of power dividers and couplers.
The first products being showcased are the DOCSIS 3.1 ‘push-pull’ and ‘power doubler’ GaAs solutions in plastic and hybrid formats, These GaAs infrastructure amplifiers offer higher linearity and output power with extended 1.2GHz bandwidth.
The company is also showcasing Diplex filters that deliver very high isolation and return loss while simultaneously maintaining the lowest possible insertion loss. The higher power levels combined with extended frequency requirements of DOCSIS 3.1 place much greater demands on the passive components in the system amplifier.
The company’s platform of high performance, surface mount triplex filters, which cover the 42/54, 65/88, 85/108 MHz, and 204/258 MHz bands, are MoCA 2.0 compliant and fully footprint compatible, allowing for simplified front-end designs and quicker design cycles. Extremely high performance filter technology is needed to simultaneously support next generation MoCA systems and new DOCSIS 3.1 interfaces to the core network.
300 MHz reverse path single-ended, differential and variable gain amplifiers meet the challenges of next generation architectures because DOCSIS3.1 extends frequency bands in both the forward and reverse paths.
