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.
