GENERAL DESCRIPTION

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.
