This APS3605 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 overall linearity of each path
is maintained across the entire operating frequency

PRODUCT DESCRIPTION
range, ensuring low distortion effects on each output
signal.
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.
