This APS3623 active splitter from ANADIGICS accepts
a broadband RF input from 50 MHz to 1 GHz and splits
the signal to provide three broadband RF outputs with
minimal degradation of quality. The single-package
surface mount device amplifies the input using highly
linear, low noise amplification stages, and couples
the amplified signal to three separate output paths
that each can drive either analog video, digital video
or digital data tuners. The APS3623 offers a special

PRODUCT DESCRIPTION
frequency/gain profile, which compensates for inband
signal attenuation caused by MoCA line filters.
Requiring a single voltage supply of +5 V, the active
splitter is manufactured using ANADIGICS’ highly
reliable GaAs MESFET process. The small surface
mount QFN packaging makes this device ideal for use
in today’s set-top boxes, televisions and video tuner
cards requiring multiple-tuner solutions.
