DESCRIPTION

The ISG56525 is a low noise, low distortion hybrid amplifier specified

for use in return path HFC Cable TV applications. The ISG56525 is

comprised of 100% surface mount components, including high

performance 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.
