New ANADIGICS RF Amplifier Enables Higher Data Rates to More CATV Subscribers on DOCSIS® 3.0 Networks

ARA2021 Device Delivers Higher Output Power With Lower Standby Current

WARREN, NJ--(Marketwire - October 24, 2010) - ANADIGICS, Inc. (NASDAQ: ANAD) today introduced its latest upstream path RF amplifier optimized for use in DOCSIS-compliant cable modems, CATV set-top boxes (STBs), residential gateways and Embedded-Multimedia Terminal Adapter (E-MTA) applications. Designed to support a new high power operation mode specified in the recently-amended DOCSIS 3.0 telecommunications standard, the ANADIGICS ARA2021 provides the fastest broadband upstream pipe to subscribers located further from the CATV head end. The industry-leading performance of this device enables more subscribers on the network to take advantage of the fastest possible data transmission rates, ensuring a quality broadband experience. At the same time, the ARA2021 supports energy "green" initiatives by reducing power consumption by up to 97% in standby mode.

Managed by CableLabs, a non-profit research and development industry consortium, the DOCSIS standard was created to help cable operators transition their businesses from solely delivering TV programming to becoming full-service providers of video, voice and data services. DOCSIS 3.0 is the current version of the standard, which includes a number of features, including channel bonding techniques that provide cable operators with a flexible way to boost end-user data speeds to as much as 160 Mbps downstream and 120 Mbps upstream.

"Based on the broadband consumers' growing appetite for bandwidth-intensive applications such as remote hard drive backup, sharing of large data files, and HD video uploads, industry analysts foresee steady growth in the coming years for DOCSIS 3.0-compliant products," said Joe Cozzarelli, Senior Director, Broadband RF Product Line, ANADIGICS. "We've developed the ARA2021 amplifier to meet the demanding requirements of CATV networks that can deliver the highest data rates and extended reach, providing the end-user with an exceptionally satisfying broadband experience."

The ARA2021 is a highly linear, programmable gain amplifier that includes a digitally controlled, multiple-stage precision step attenuator and provides extremely low harmonics and superior distortion performance at high output power levels. This performance enables the amplifier to overcome long loop attenuation created by directional couplers, taps, attenuators, and other input losses, thus ensuring a high quality signal at the head end.

Additional facts and highlights about the ARA2021:

  • Supports linear output power levels up to +67 dBmV (single channel).
  • Integrates a precision step attenuator with up to 49 dB of attenuation in 1dB increments.
  • Features 35 dB of RF voltage gain (at minimum attenuation).
  • Offered in a 20-pin, 4 mm x 4 mm x 1mm MLPQ (QFN) package.
  • Operates in a frequency range from 5 MHz to 85 MHz.
  • Includes a low-power Transmit Disable (standby) mode that consumes only 35mW.

Engineering evaluation samples of ANADIGICS' ARA2021 amplifier are available now for qualified opportunities.
