ANADIGICS Introduces New Integrated 1GHz RF Amplifier to Enhance Tuner Performance in Cable Boxes and TVs

Integrated 1 GHz Product Features Low Noise, Wide Dynamic Range Gain Control and Balanced Output

WARREN, N.J., May 21 -- ANADIGICS, Inc. (NASDAQ: ANAD) has announced the availability of the ABA3130, a single-chip, low-noise, high linearity RF amplifier with integrated gain control. This device is the latest addition to ANADIGICS' portfolio of RF products for cable TV front end applications. Designed to replace existing discrete solutions, the fully integrated ABA3130 improves receiver performance in a growing number of cable TV digital set-top boxes and analog and digital TVs.

To ensure compatibility with tuners being developed for the 1 GHz cable systems soon to be rolled out around the world, the ANADIGICS ABA3130 features wideband operation of 50 MHz to 1.1 GHz. ANADIGICS is already shipping the ABA3130 RF amp to a leading cable box manufacturer.

The ABA3130 exhibits a typical noise figure of 4.5 dB at 5 dB gain, which enables clearer analog pictures and better reception on digital channels. The ABA3130 also offers a wide dynamic gain control range of 37 dB, to prevent overloading tuner front ends. The device delivers exceptional linearity over the full dynamic gain range, minimizing distortion and ensuring a high quality signal and crystal-clear video.

"ANADIGICS' leadership products for Broadband are addressing the ever increasing demand on bandwidth in CATV networks. The ABA3130 addresses the 1GHz upgrade in the industry and is based on our GaAs proprietary process technology for high reliability and wideband operation," said Ron Michels, Senior Vice President and General Manager of Broadband Products at ANADIGICS. "According to In-Stat market research, sales of cable set-top boxes increased nearly 80% between 2005 and 2006, to 27.5 million units worldwide. As integrated tuners continue to penetrate this market, we anticipate an increase in the need for companion products like the ABA3130.

The ANADIGICS ABA3130 accepts a single-ended (unbalanced) input and converts it to a differential (balanced) output, which some integrated tuners require for optimal performance. This feature eliminates the need for a separate balun transformer on the circuit board. The high level of integration and 3 x 3 x 1 mm form factor of the ABA3130 further reduce the amount of board space required for RF front-end solutions.

ANADIGICS' ABA3130 operates from a single 5 volt supply. It is offered in a 12-pin surface-mount QFN package that is manufactured using a material set consistent with the European Union's Restriction of Hazardous Substances (RoHS).
