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 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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.

Notes:
1. Application circuits are available for other supply voltages. Contact ANADIGICS broadband engineering for more detail.
2) The BIAS pin is normally grounded for 3.3 V applications. However, the device linearity may be improved at VDD = 5 V
by applying an external voltage on the pin, using a voltage divider circuit between VDD and GND.
3) L2 and C3 may be necessary for matching. The values are determined by the application, as needed.
