PRODUCT DESCRIPTION
ThisAPS3605 active splitter fromANADIGICS 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 Figure 1: Functional Block Diagram range, ensuring low distortion effects on each output signal.
