MACOM showcases CATV and broadband devices for high-speed cable networks at ANGA COM

In booth P28 at the ANGA COM 2014 Exhibition & Congress for Broadband, Cable and Satellite in Cologne, Germany (20-22 May), M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog, RF, microwave and millimeter-wave applications) will showcase 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 (CPE), 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, notes the firm.

MACOM is addressing this with a suite of new product families being showcased at ANGA COM:

* DOCSIS3.1 push-pull and power doubler gallium arsenide (GaAs) infrastructure amplifiers in plastic and hybrid formats, offering multiple system operators (MSOs) higher linearity and output power with extended 1.2GHz bandwidth.

* 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 DOCSIS3.1, place much greater demands on the passive components in the system amplifier, says MACOM. Passives need to exhibit multi-octave flat response and not contribute to system distortion.

* A platform of high-performance, surface-mount triplex filters covering the 42/54, 65/88, 85/108 and 204/258MHz bands that are MoCA 2.0 compliant and fully footprint compatible, allowing 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, says MACOM.

* 300MHz reverse-path single-ended, differential and variable-gain amplifiers that 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.

The event will be attended by MACOM’s CATV product managers Graham Board and John Fenton.
