DESCRIPTION
The ISG56518 is a low noise, low distortion hybrid amplifier specified for
use in return path HFC Cable TV applications. The ISG56518 is
comprised of 100% surface mount components, including high perfor-
mance silicon transistors. It features excellent noise, gain, and thermal
stability across a wide range of operating conditions and frequencies.The
amplifiers are manufactured to ISO9002 standards, are very rugged and
exhibit excellent unit to unit uniformity.
