PRODUCT DESCRIPTION
The ACA3748 is a GaAs Hybrid Amplier for CATV
HFC distribution systems. It consists of two pairs of
parallel ampliers that are optimized for exceptionally
low distortion and noise gure with input and output
transient voltage protection. The ACA3748 is offered
in a standard SOT-115J package.
