● All-Digital CATV Set-Top Boxes with Multiple Tuners● Multiple-Tuner TVs and TV Tuner Cards S26 Package 12 Pin QFN 3 mm x 3 mm x 1 mm This APS3607 active splitter from ANADIGICS accepts a broadband RF input from 50 MHz to 1002 MHz and splits the signal to provide four broadband RF outputs with minimal degradation of quality. The singlepackage surface mount device amplifies the input using highly linear, low noise amplification stages, and couples the amplified signal to four separate output paths that each can drive digital video tuners. The overall linearity of each path is maintained across the entire operating frequency range, ensuring low PRODUCT
