Product Information

1 GHz Three-way Active Power Splitter PRELIMINARY DATA SHEET - Rev 1.1 APS3623 Optimized for MoCA-Enabled Subscriber Equipment • Single Input, Triple Output Design • Gain profile compensates for inband MoCA line filter attenuation • Wideband Operation to 1 GHz • Supports both Analog TV and Digital TV Lineups • Nominal 5 dB Gain • 4.5 dB Typical Noise Figure • Single +5 V Supply • Current adjust pin for optimizing distortion performance • High Linearity, Low Distortion • Single-Ended 75 Ohm Inputs/Outputs • Materials set consistent with RoHS directives FEATURES APS 362 3 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 APS3623 active splitter from ANADIGICS 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 www.DataSheet4U.com 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 APS3623 offers a special S26 Package 12 Pin QFN 3 mm x 3 mm x 1 mm PRODUCT DESCRIPTION frequency/gain profile, which compensates for inband signal attenuation caused by MoCA line filters. Requiring a single voltage supply of +5 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.
