Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has introduced a family of hybrid line amplifier modules optimized for DOCSIS 3.1 infrastructure equipment.
The new ACA47XX line amplifiers integrate the firm's proven surface-mount solutions and passive components in an industry-standard SOT-115J package. Equipment manufacturers can select from push-pull and power doubler configurations, with various gain and output power levels to ensure optimal DOCSIS 3.1 system performance.
"These solutions combine our field-proven, highly linear GaAs [gallium arsenide] technology with a high-power GaN [gallium nitride] output stage to deliver exceptional output power over the full DOCSIS 3.1 frequency band," says James Martin, senior business development director of Infrastructure Products. "With global data consumption continuing to rise, our new DOCSIS 3.1 hybrid line amplifier modules stand out as critical enablers for the anticipated major industry-wide infrastructure upgrade."
The ACA47XX hybrid line amplifier modules combine the firm's GaAs-based MESFET and proprietary high-linearity pHEMT technologies with a GaN output stage (power doublers only) in a common, industry-standard SOT-115J package (providing greater design flexibility across systems) for CATV infrastructure applications. The line amplifiers offer what is claimed to be 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. Two members of the new product family (the ACA4741 and ACA4788) offer what is reckoned to be record output power to support both analog/digital and completely digital CATV systems. The solutions enable Node+0 system architectures without active components downstream of the fiber or R-MACPHY node.
