MACOM showcasing CATV and broadband devices for high-speed cable networks

In booth 432 at the SCTE Cable-Tec Expo’14 in Denver (23-25 September), M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes analog semiconductors, components and subassemblies for analog, RF, microwave and millimeter-wave applications) is showcasing its portfolio of CATV and broadband devices enabling the evolution of modern cable networks.

To keep pace with the exponential growth in data demand while leveraging previously deployed fiber and copper, cable networks are working toward the deployment of DOCSIS 3.1 equipment, says MACOM. 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 – essentially a full refresh of the equipment toolkit, the firm adds.

MACOM’s suite of new product families includes the following:

  • DOCSIS3.1 push-pull and power doubler gallium arsenide (GaAs) infrastructure amplifiers in SMT plastic format, offering multiple system operators higher linearity and output power with extended 1.2GHz bandwidth.
  • Diplex filters that deliver high isolation and return loss while simultaneously maintaining the lowest possible insertion loss. The higher power levels combined with extended frequency requirements of DOCSIS3.1 place much greater demands on the passive components in the system amplifier. Passives need to exhibit multi-octave flat response and not contribute to system distortion.
  • A platform of surface-mount triplex filters covering the 42/54, 65/85, 85/105 and 204/258MHz bands that 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.
  • 300MHz reverse path single-ended, differential and variable gain amplifiers, which meet the challenges of next-generation architectures because DOCSIS3.1 extends frequency bands in both the forward and reverse paths.
  • FTTx amplifiers that have been developed specifically to meet radio frequency over glass (RFoG) and passive optical network (PON) system requirements.
