Product Details

The ADA4304-2 is a 75 Ω 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 ADA4304-2 is fabricated using Analog Devices, Inc. proprietary silicon-germanium (SiGe), complementary bipolar process, enabling it to achieve very low levels of distortion with a noise figure of 4 dB. The part provides 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 ADA4304-2 is available in a 16-lead LFCSP and operates in the extended industrial temperature range of −40°C to +85°C.
