PRODUCT DESCRIPTION
This APS3611 active splitter from ANADIGICS accepts
a broadband RF input from 50 MHz to 870 MHz and
splits the signal to provide two 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 two separate output paths that each
can drive either analog video, digital video or digital

12 Pin QFN
3 mm x 3 mm x 1 mm
data tuners. The APS3611 offers a special frequency/
gain profile, which compensates for inband signal
attenuation caused by MOCA line filters.
Requiring a single voltage supply of +5 V, and operable
down to +3.3 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.
