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, NJ, May 21, 2007 - 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).
