ANADIGICS has introduced a new family of hybrid line amplifier modules optimized for DOCSIS 3.1 infrastructure equipment. The new ACA47XX line amplifiers integrate surface mount solutions and passive components in an industry-standard SOT-115J package. Equipment manufacturers are able to select from push-pull and power doubler configurations, with various gain and output power levels to ensure optimal DOCSIS 3.1 system performance.
ANADIGICS ACA47XX hybrid line amplifier modules combine MESFET and proprietary high-linearity pHEMT technologies with a GaN output stage (power doublers only) in a common SOT-115J package to deliver outstanding performance and reliability in CATV infrastructure applications. These line amplifiers 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. Two members of the new product family, the ACA4741 and ACA4788, offer record breaking output power to support both analog/digital and completely digital CATV systems. These solutions deliver world-class performance to enable Node+0 system architectures without active components downstream of the fiber or R-MACPHY node.
The DOCSIS 3.1 Hybrid Line Amplifier Module Family is a family of +24 Vdc solutions with multiple gain, and output power level options. The modules have exceptionally low MER, BER, CTB, CSO, and cross modulation distortion characteristics. The GaN output stage increases output power, ruggedness, and efficiency (power doublers only) and GaAs driver stage provides exceptional linearity, reliability, and low noise. They are available in industry standard SOT-115J package to provide greater design flexibility across systems.
