GENERAL DESCRIPTION
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.
Figure 2.
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.
