PAs deliver high linearity, low noise for improved signal integrity

Warren, N.J.—ANADIGICS Inc. has launched its ABA3101 and ABA3115 balanced low noise linear power amplifiers (PAs) designed to generate high signal integrity in CATV set-top box, distribution and drop applications.

The ABA3101 is a +8V supply design that delivers +34dBmV per channel of highly linear output power, together with 12dB of RF gain. Housed in a thermally enhanced package, the ABA3101 maintains composite second order (CSO) and composite triple beat (CTB) distortion products below -69 dBc, and provides a typical noise figure less than 3.2dB across the 1GHz CATV band.

ANADIGICS' ABA3115 operates from a +5V supply to provide +25dBmV per channel of linear output power and 15dB of RF gain. Operating up to 870MHz, this GaAs IC maintains CSO and CTB distortion products below -70 dBc, and provides a typical low noise figure of 2.7dB. The ABA3115 also incorporates a shutdown feature under logic control, whereby power consumption is reduced to 15mW.

The ABA3101 and ABA3115, as well as the previously released ABA3100, ADA10000 and ADA10001, are each housed in a 16-pin surface mount package, providing a common platform for CATV product designers.

Pricing: In 3,500 unit quantities, the ABA3101 costs $6 and the ABA3115 is $5.60 each.
Availability: Now.
Datasheets: ABA3101 and ABA3115.
