DESCRIPTION
The ISG52124-L is a low Power 12V Broadband hybrid amplifier
module developed for return path optical and RF applications
in (HFC) CATV systems.The ISG52124-L 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.
