APS3623 1 GHz Three-way Active Power Splitter Optimized for MoCA-Enabled Subscriber Equipment PRELIMINARY DATA SHEET - Rev 1.3 FEATURES • 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 +3.3 V or +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 S26 Package 12 Pin QFN 3 mm x 3 mm x 1 mm 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 PRODUCT DESCRIPTION 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 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 frequency/gain profile, which compensates for inband signal attenuation caused by MoCA line filters. Requiring a single voltage supply of +3.3 V or +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.
