The ADA4304-3/ADA4304-4 are 75 Ω active splitters for use in applications where a lossless signal split is required. Typical applications include multituner digital set-top boxes, cable splitter modules, multituners/digital cable ready (DCR) televisions, and home gateways where traditional solutions require discrete passive splitter modules with separate fixed gain amplifiers. Set-top boxes Residential gateways CATV distribution systems Splitter modules Digital cable ready (DCR) TVs
The ADA4304-3/ADA4304-4 are fabricated using the Analog Devices, Inc., proprietary silicon germanium (SiGe), complementary bipolar process, enabling them to achieve very low levels of distortion with a noise figure of 4.6 dB. The parts provide low cost alternatives that simplify designs and improve system performance by integrating a signal splitter element and a gain block into a single IC. The ADA4304-3/ADA4304-4 are available in a 16-lead LFCSP and operate in the extended industrial temperature range of −40°C to +85°C.
