Active RF Splitter

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.
