The single-package surfacemountdeviceamplifiestheinputusinghighly linear,lownoiseamplificationstages,andcouplesthe amplified signal to three separate output paths that each can drive either analog video, digital video or digitaldatatuners.Theoveralllinearityofeachpath ismaintainedacrosstheentireoperatingfrequency S26 Package 12 Pin QFN 3 mm x 3 mm x 1 mm PRODUCT DESCRIPTION range,ensuringlowdistortioneffectsoneachoutput signal. Requiringasinglevoltagesupplyof+5V,andoperable down to +3.3 V, the active splitter is manufactured usingANADIGICS' 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-tunersolutions.
