GENERAL DESCRIPTION

3
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.
