Anadigics Launches Two GaN Line Amplifiers For CATV
Devices support DOCSIS 3.1 networks, including Node+0 architectures
Anadigics has today introduced two new high-power GaN line amplifiers for CATV systems. The ACA2455 and ACA2456 line amplifiers support full DOCSIS 3.1 bandwidth, operating up to 1.2GHz, while supporting legacy bands down to 50MHz. These amplifiers also enable Node+0 system architectures without active components downstream of the fibre node.
"Innovation that enables reliably superior product performance has always been part of Anadigics' DNA," said Tim Laverick, senior vice president of Infrastructure Products at Anadigics.
"Our new line amplifiers exemplify this fundamental drive by combining Anadigics' field-proven, highly linear GaAs technology with a high-power GaN output stage, delivering the industry's highest output power over the full DOCSIS 3.1 frequency band."
With Node+0 configurations, fibre is run deeper into the network, eliminating the need for downstream RF amplifiers. Node+0 is the natural evolution of node splitting and the shift to 'fibre deep' architectures as MSOs continue to seek out new ways to increase system bandwidth by shrinking service groups to reduce the number of homes served by each node.
This architecture also significantly simplifies network design, reduces maintenance costs, and decreases deployment time for new build outs. As demand for faster data speeds accelerates, the total number of deployed nodes is expected to increase by up to 1000 percent according to some estimates.
Anadigics' ACA2455 and ACA2456 line amplifiers combine the company's MESFET technology with a GaN output stage in a 16-lead surface mount package.
The ACA2455 line amplifier provides 28dB gain with +73dBmV composite output power, while the ACA2456 solutions offers 18dB gain with +76dBmV composite output power.
