GENERAL DESCRIPTION

The ADA4302-4 is used as an active element in applications

where a lossless signal split is required. Typical applications

include multituner cable set-top boxes, cable splitter modules,

multituner televisions, and home gateways where traditional

solutions have consisted of discrete passive splitters followed by

separate fixed gain amplifiers. The ADA4302-4 is a low cost

alternative solution that simplifies designs and improves system

performance by integrating a signal splitter element and gain

element into a single IC solution.

The ADA4302-4 features four differential outputs. The

differential architecture allows systems designed with the

ADA4302-4 to maintain excellent linearity throughout the

CATV band. The ADA4302-4 can also be configured for

applications that require fewer than four outputs. Outputs

may be configured independently from one another.
