ANADIGICS
PRODUCT DESCRIPTION
ThisAPS3611 active splitter fromANADIGICS 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 Figure 1: Functional Block Diagram data tuners. The APS3611 offers a special frequency/ gain profile, which compensates for inband signal attenuation caused by MOCA line filters.
