Description

The APS3611R is an active splitter from ANADIGICS that 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. It is a single-package surface mount device that amplifies the input using highly linear, low noise amplification stages, and couples the amplified signal to two separate output paths that can drive either analog video, digital video, or digital data tuners. The APS3611R offers a special frequency/gain profile that compensates for inband signal attenuation caused by MOCA line filters.
