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.
