ANADIGICS has 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.
ANADIGICS’ ACA2455 and ACA4733 line amplifiers combine the Company’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.
High-power line amplifier family provides highest single-device output power to support both analog/digital and completely digital CATV systems. They enable Node+0 system architectures without active components downstream of the fiber node and GaN output stage increases output power, ruggedness and efficiency.
