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.
