Anadigics launches GaN-based DOCSIS 3.1 CATV infrastructure line amplifiers with highest RF power per Watt consumed

At ANGA COM 2015 Exhibition & Congress for Broadband, Cable and Satellite in Cologne, Germany (9-11 June), Anadigics Inc of Warren, NJ, USA has introduced two high-power gallium nitride (GaN) infrastructure line amplifiers for CATV systems. 

The ACA2455 and ACA4733 power doublers are optimized for fiber deep, Node+0 networks, and node segmentation/split upgrades. With only 12.7W of DC power consumption, the new line amplifiers are claimed to offer the lowest cost per bit for all-digital content delivery (efficiency that helps MSOs to better manage operating costs over the life of the network).

"MSOs aim to enhance services while minimizing expenses," says James Martin, senior business development director of Infrastructure Products. "Our new DOCSIS 3.1 GaN line amplifiers are optimized to support both of these objectives. These power doublers not only deliver the output power and linearity required for DOCSIS 3.1 applications, but also provide exceptional efficiency for energy-saving 'green' networks," he adds.

The ACA2455 and ACA4733 line amplifiers combine the firm's gallium arsenide (GaAs) MESFET technology (for a driver stage with exceptional linearity and reliability) with a GaN output stage (to increase output power, ruggedness and efficiency). The highly linear power doublers provide 28dB gain, +63dBmV per channel output power, and +73.2dBmV total composite power. The ACA2455 and ACA4733 GaN line amplifiers also offer what is claimed to be exceptional composite triple beat (CTB), composite second order (CSO), cross modulation, carrier-to-intermodulation noise (CIN), and modulation-error and bit-error ratio (MER and BER) characteristics for optimal performance in a fully loaded spectrum.

The firm's line amplifier family is claimed to provide the highest single-device output power to support both analog/digital and completely digital CATV systems, as well as the industry's highest performance to enable Node+0 system architectures without active components downstream from the fiber node.
