PRODUCT DESCRIPTION
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single-
package surface mount device amplies the input
using highly linear, low noise amplication stages,
and couples the amplied 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+3.3V,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.
