Anadigics launches 870MHz hybrid line amplifiers for CATV

Anadigics Inc of Warren, NJ, USA has launched a family of 24V 870MHz hybrid line amplifiers, designed mainly for use in CATV distribution systems.

“Anadigics introduced the first commercially available integrated circuit cable TV line amplifiers,” says Ray Aubert, senior product marketing manager. Anadigics shipped more than 20 million CATV line amplifiers in individual surface-mount packages over the past 15 years.

The new products mark the first time that Anadigics has made its CATV line amplifier technology available in the industry-standard SOT115J hybrid package.

The new hybrid-packaged devices, which deliver high gain, low noise, and superior distortion performance it is claimed, should enable manufacturers to rapidly assimilate Anadigics’ solutions into existing CATV distribution nodes and line extenders. “These new hybrid products enable us to address growing markets in Asia and eastern Europe, by harnessing Anadigics’ RF technology and design capability to provide customers with a competitively priced, drop-in replacement that out-performs other hybrid line amps,” Aubert claims.

“Extra testing and special circuitry has been added to maximize the ESD performance,” says Doug Johnson, VP of CATV Amplifier Products. “This is required to achieve the ruggedness needed for the CATV infrastructure applications,” he adds.

The new product family includes three power-doubler hybrid line amplifiers (the ACA3742, ACA 3747 and ACA 3753, with 21.5dB, 25dB and 28dB of gain, respectively) and two push-pull hybrid line amplifiers (the ACA3722 and ACA3733, with 21.5dB and 34dB of gain, respectively):

The ACA3722 and ACA3742 will be available for sampling in second-quarter 2009, followed shortly by the ACA3753. The ACA3733 and ACA3747 will be available in third-quarter 2009.
