Anadigics Expands Line Amplifiers Portfolio With 1 GHz Products

Warren, NJ -- Anadigics, Inc. introduced five new line amplifier ICs for CATV infrastructure applications. These amplifiers help CATV service providers increase their system bandwidth, allowing them to offer additional digital services, including digital simulcast of analog channels, high-definition television (HDTV), and video on demand (VOD).

Anadigics' line amplifier ICs support picture quality by offering linearity and noise figure to ensure minimum signal degradation over a frequency range from 40 MHz to 1 GHz. The devices maintain low composite triple beat (CTB), composite second order (CSO), and cross modulation distortion characteristics for a fully-loaded spectrum. The amplifiers are manufactured using Anadigics' MESFET process. To provide maximum flexibility, designers can choose between 12 V or 24 V ICs.

"Anadigics' new amplifiers demonstrate our commitment to innovation and product excellence, which are key drivers behind our growth strategy," said Ron Michels, Senior Vice President and General Manager of Broadband Products at Anadigics. "We remain the world's leading supplier of GaAs line amplifier ICs for CATV infrastructure applications, by offering MESFET products that provide significant advantages in performance and reliability compared with existing hybrid approaches."

The ACA0862B andACA0862D are 12 V devices designed to provide high power levels, and can serve as system amplifier output stages. The devices each have 11 dB of gain, and are easily cascaded to form an IC equivalent of a hybrid amplifier. The ACA0862B features lower power dissipation than the ACA0862D, for applications with lower output power needs.

The ACA1206 is another 12 V device that is optimized to serve as a system amplifier input stage. With 14 dB of gain, the amplifier can be used to drive an output stage device, such as the ACA0862B or ACA0862D. Together, the ACA1206 and an output stage are cascaded to form an IC equivalent of a hybrid amplifier.

The ACA2402 and ACA2407 are 24 V devices that can be used individually as replacements for hybrid amplifiers. The ACA2402 serves as a push-pull amplifier, while the ACA2407 functions as a power doubler.

All five of ANADIGICS' new 1 GHz line amplifiers are offered in a 16-pin wide-body SOIC surface-mount package with a built in heat slug for enhanced thermal protection. The products are manufactured using a materials set consistent with the European Union's Restriction of Hazardous Substances (RoHS) directive.
