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.

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.
