Anadigics expands surface-mount line amplifier family for 1.2GHz DOCSIS 3.1 systems

In booth 608 at the Society of Cable Telecommunications Engineers (SCTE) Cable-Tec Expo 2013 in Atlanta (22-24 October), broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA has announced that it has expanded its surface-mount line amplifier family for data over cable service interface specification (DOCSIS) system standard version 3.1.

The new 12V and 24V line amplifiers deliver what is claimed to be exceptional linearity and output power, enabling CATV service providers to increase system bandwidth in support of DOCSIS 3.1. By extending frequencies to 1.2GHz, DOCSIS 3.1 enables higher data speeds as well as additional high-definition television (HDTV) and video on demand (VOD) services.

“Our new DOCSIS 3.1 surface-mount line amplifiers deliver industry-leading linearity and output power across an expanded frequency range to support the newest generation of 1.2GHz downstream equipment,” claims Tim Laverick, VP of Infrastructure Products. “We are helping MSOs confidently upgrade their network hardware as they roll out exciting new services made possible by DOCSIS 3.1.”

Operating over frequencies of 40–1200MHz, the new 12V ACA1210, ACA1212 and ACA1216 output amplifiers (with current consumption of 250mA, 530mA and 500mA, and typical gain of 19dB, 12dB and 27dB, respectively) run from a 12V supply. The new ACA2431 and ACA2449 power doubler amplifiers (GaN HEMT and GaAs MESFET, respectively, drawing current of 425mA and 490mA, with gain of 28dB and 25dB) and the new ACA2461 GaAs MESFET push-pull amplifier (drawing 290mA, with gain of 25dB) run from a 24V supply. These new line amplifiers join the ACA2429 gallium nitride (GaN) power doubler (launched in July) in providing high signal fidelity over extended frequencies up to 1.2GHz. The surface-mount solutions offer what is claimed to be outstanding bit error rate (BER), 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.

Anadigics’ DOCSIS 3.1 line amplifier family leverages the firm’s proven high-linearity gallium arsenide (GaAs) MESFET process for reliability (to maximize up-time) along with GaN HEMT technology( for high output power and optimum power efficiency).
