PRODUCT DESCRIPTION
The ACA2786 is a GaAs Hybrid Amplier for CATV
HFC distribution systems. It consists of two pairs of
parallel ampliers that are optimized for exceptionally
low distortion and noise gure with input and output
transient voltage protection. The ACA2786 is offered
in a standard SOT-115J package.
