Product Information

Optimized for MOCA-Enabled Subscriber equipment • Single Input, Double Output Design • Gain profile compensates for inband MOCA line filter attenuation • Wideband Operation to 870 MHz • Supports both Analog TV and Digital TV Lineups • Nominal 3 dB Gain • 5 dB Typical Noise Figure • Single +5 V Supply, with Operation Down to +3.3 V • Current Adjust pin for optimizing distortion performance • High Linearity, Low Distortion • Single-Ended 75 Ohm Inputs/Outputs • RoHS Compliant Package 870 GHz Two-way Active Power Splitter PRELIMINARY DATA SHEET - Rev 1.1 APS3611 FEATURES AP S3 61 1 APPLICATIONS • Analog/Digital and All-Digital CATV Set-Top Boxes with Multiple Tuners and Multimedia Over Coax Alliance (MOCA) Functionality • Multiple-Tuner TVs, TV Tuner Cards and Broadband Media Centers This APS3611 active splitter from ANADIGICS 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 www.DataSheet4U.com 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 S26 Package 12 Pin QFN 3 mm x 3 mm x 1 mm data tuners. The APS3611 offers a special frequency/ gain profile, which compensates for inband signal attenuation caused by MOCA line filters. 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.
