Product Information

ADVANCED PRODUCT INFORMATION - Rev 0.1 Eight-way Active Power Splitter APS3628 • Single Input, Eight Output Design • Wideband Operation to above 1 GHz • Nominal 3.2 dB Gain • 4.7 dB Typical Noise Figure • Single +3.3V or +5V Supply • High Linearity, Low Distortion • Current adjust pin for optimizing distortion performance • Single-Ended 75 Ohm Inputs/Outputs • Materials set consistent with RoHS Directives FEATURES APS 362 8 APPLICATIONS • All-Digital CATV Set-Top Boxes with Multiple Tuners • Home Gateways, Multiple-Tuner TVs and Set-top boxes S34 Package 24 Pin QFN 4 mm x 4 mm x 1 mm This APS3628 active splitter from ANADIGICS accepts a broadband RF input from 50 MHz to 1002 MHz and splits the signal to provide eight broadband RF outputs with minimal degradation of quality. The singlepackage surface mount device amplifies the input using highly linear, low noise amplification stages, www.DataSheet4U.com and couples the amplified signal to eight 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 distortion effects on each output signal. Requiring a single voltage supply of either +3.3V 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 multipletuner solutions.
