PRODUCT DESCRIPTION
ThisAPS3611activesplitterfromANADIGICSaccepts
abroadbandRFinputfrom50MHzto870MHzand
splitsthesignaltoprovidetwobroadbandRFoutputs
withminimaldegradationofquality.Thesingle-package
surfacemountdeviceampliestheinputusinghighly
linear,lownoiseamplicationstages,andcouplesthe
ampliedsignaltotwoseparateoutputpathsthateach

datatuners.TheAPS3611offersaspecialfrequency/
gain prole, which compensates for inband signal
attenuationcausedbyMOCAlinelters.
Requiringasinglevoltagesupplyof+5V,andoperable
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.

ELECTRICAL CHARACTERISTICS
Table 2: Absolute Minimum and Maximum Ratings
Stresses in excess of the absolute ratings may cause permanent damage.
Functional operation is not implied under these conditions. Exposure
to absolute ratings for extended periods of time may adversely affect
reliability.
Table 3: Operating Ranges
The device may be operated safely over these conditions; however, parametric performance is guaranteed only
over the conditions dened in the electrical specications.
