Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has introduced six surface-mount line amplifiers optimized for DOCSIS 3.1 CATV infrastructure applications. The firm's portfolio of DOCSIS 3.1 products includes line amplifiers, reverse path amplifiers, edge QAM amplifiers, and gain blocks.
The DOCSIS 3.1 line amplifiers combine the firm's gallium arsenide (GaAs)-based MESFET and high-linearity pHEMT technologies with a gallium nitride (GaN) output stage (power doublers only). The new ACA2416, ACA2419, ACA2454, ACA2457, ACA2458 and ACA2463 all offer exceptional composite triple-beat (CTB), composite second-order (CSO), cross-modulation, carrier-to-intermodulation noise (CIN), modulation-error ratio (MER), and bit-error ratio (BER) characteristics for optimal performance in a fully loaded spectrum, claims the firm.
The ACA2458 joins the ACA2456, ACA4741, and ACA4788 in the new 4X-class product family. These solutions offer four times the power of first-generation GaN line amplifiers. This power, coupled with other performance characteristics, enables Node+0 system architectures without active components downstream of the fiber or R-MACPHY node.
