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