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.
