ANADIGICS, Inc., a world leader in radio frequency (RF) solutions, introduced two new high-power GaN infrastructure line amplifiers for CATV systems at ANGA COM 2015. The ACA2455 and ACA4733 power doublers are optimized for fiber deep, Node+0 networks, and node segmentation/split upgrades by delivering world-class output power, linearity and efficiency. With only 12.7 Watts of DC power consumption, these new line amplifiers offer the lowest cost per bit for all-digital content delivery. This efficiency helps MSOs better manage operating costs over the life of the network.

"MSOs aim to enhance services while minimizing expenses," said James Martin, senior business development director of Infrastructure Products at ANADIGICS. "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."

ANADIGICS' ACA2455 and ACA4733 line amplifiers combine the bompany's MESFET technology with a GaN output stage to deliver exceptional performance and reliability in CATV infrastructure applications. These highly linear power doublers provide 28 dB gain, +63 dBmV per channel output power, and +73.2 dBmV total composite power. The company's ACA2455 and ACA4733 GaN line amplifiers offer 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.

ANADIGICS High-Power Line Amplifier Family Key Facts and Highlights:

  • Highest single-device output power to support both analog/digital and completely digital CATV systems
  • Industry's highest performance to enable Node+0 system architectures without active components downstream of the fiber node
  • GaN output stage increases output power, ruggedness and efficiency
  • GaAs driver stage provides exceptional linearity and reliability
