ADA4303-2:  1:2 Single-Ended, Low Cost Active RF Splitter

Product Details

The ADA4303-2 is a 75 Ω two-output active splitter for use in applications where a lossless signal split is required. Typical applications include multituner digital set-top boxes, cable splitter modules, multituner/digital cable ready (DCR) televisions, and home gateways where traditional solutions require discrete passive splitter modules with separate fixed gain amplifiers.

The ADA4303-2 is a low cost alternative that simplifies designs and improves system performance by integrating a signal splitter element and a gain block into a single IC. The ADA4303-2 is available in a 12-lead chip scale package (LFCSP_VQ) and operates in the extended industrial temperature range of -40°C to +85°C.
