Product Information

1 GHz Three-way Active Power Splitter FEATURES APS3605 PRELIMINARY DATA SHEET - Rev 1.4 • Single Input, Triple Output Design • Wideband Operation Beyond 1 GHz • Supports both Analog TV and Digital TV Lineups • Nominal 3 dB Gain • 5.5 dB Typical Noise Figure • Single +5 V Supply, with Operation Down to +3.3 V • High Linearity, Low Distortion • Current Adjust Pin for optimizing distortion performance • Single-Ended 75 Ohm Inputs/Outputs • RoHS Compliant Package AP S3 60 5 APPLICATIONS • Analog/Digital and All-Digital CATV Set-Top Boxes with Multiple Tuners • Multiple-Tuner TVs, TV Tuner Cards and Broadband Media Centers This APS3605 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 www.DataSheet4U.comthree separate output paths that amplified signal to 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 S26 Package 12 Pin QFN 3 mm x 3 mm x 1 mm PRODUCT DESCRIPTION range, ensuring low distortion effects on each output signal. 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.
