Anadigics' GaN power doubler chosen by European manufacturer for DOCSIS 3.1 CATV equipment

Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its ACA2429 gallium nitride (GaN) power doubler surface-mount IC (launched in July 2013) in support of new DOCSIS 3.1 CATV infrastructure equipment. Using the DOCSIS 3.1 standard, MSOs (multi-system operators) can increase network capacity and offer faster speeds with higher quality of service, says Anadigics.

“CATV service providers worldwide are sharply focused on expanding their customer base in the face of alternative broadband technologies,” says Tim Laverick, vice president of Infrastructure Products. “To help them succeed, network equipment manufacturers are leveraging our world-class DOCSIS 3.1 infrastructure solutions,” he adds. “The ACA2429 power doubler, now shipping in production volume to a leading European manufacturer, provides reliable, linear power amplification over an expanded frequency range to help CATV service providers offer higher data rates and take full advantage of all that DOCSIS 3.1 has to offer.”

The ACA2429 line amplifier leverages the firm’s MESFET technology and a GaN output stage, which increases power efficiency and minimizes the operating (bias) current. The power doubler provides 25dB gain with +60dBmV output power and 1.2GHz bandwidth, with only 10W of power consumption. Operating from a voltage of 24V, current consumption is 420mA. The ACA2429 offers what is claimed to be exceptional composite triple-beat (CTB), composite second-order (CSO), cross modulation, and carrier-to-intermodulation noise (CIN) characteristics for optimal performance in a fully loaded spectrum. With a combination of high gain, output power and linearity coupled with low current consumption and bit error rate (BER), the ACA2429 line amplifier enables higher data speeds as well as distortion-free video and audio.

Offered in a 16-lead SOIC surface-mount package, the ACA2429 line amplifier acts an alternative to hybrid line amplifier module designs.
