Anadigics hybrid line amp

Anadigics Inc. launches a new family of 1GHz hybrid line amplifiers that the company claims provides exceptional linearity and distortion performance in an industry standard SOT115J package. Leveraging the company's high performance CATV amplifier technology and manufacturing experience, the amplifiers deliver the additional channel spectrum required by multiple systems operators (MSOs) looking to upgrade infrastructure to support higher throughput applications, such as high-definition video, VOD, and high data rate internet.

Over the past 15 years Anadigics has led the line amplifier marketplace and shipped over 20 million devices in surface mount packages. Anadigics has applied this industry experience to develop new 1GHz hybrid devices that deliver unmatched levels of linearity and exceptional return loss, while providing exceptionally high tolerance to ESD, a feature that enhances ruggedness for outdoor operation.

The ACA2784 is a 1GHz power doubler that delivers 21.5dB gain and +58dBmV per channel linear output power. The ACA2782 is a 1GHz power doubler that delivers 21.5dB gain and +55dBmV per channel linear output power. The ACA2764 is a 1GHz push-pull amplifier that delivers 21.5dB gain and +40dBmV per channel linear output power. Lastly, the ACA2786 is a 1GHz power doubler that delivers 25dB gain and +58dBmV per channel linear output power.

Ray Aubert, product marketing manager for Anadigics said, "Our new 1GHz line amplifiers provide MSOs with valuable added spectrum. With today's compression technology, some MSOs are maxing out their spectrum as they add more standard and HD channels to their lineup. And as new bandwidth intensive, high data rate technologies, such as DOCSIS 3.0, gain momentum, spectrum expansion to 1GHz will become more prevalent."

Another trend in the CATV industry is to push the fiber content of hybrid fiber-coax networks deeper towards the subscriber terminal. MSOs now have the opportunity to provide systems that will support growing bandwidth demands by incorporating the latest 1GHz devices when performing node splits, or when installing new fiber nodes and system amplifiers in greenfield deployments.

Doug Johnson, VP of CATV products, Anadigics, reports, "20 million line amplifiers shipped clearly demonstrate that Anadigics' has a commanding, competitive edge in line amplifier technology. We have leveraged our vast experience in GaAs MOSFET processes to deliver industry leading performance. To assure field ruggedness, our parts have been tested to ESD levels which far exceed any other hybrid available today."
