PRODUCT DESCRIPTION
This active splitter from ANADIGICS accepts a
balanced RF input in the 50 to 860 MHz frequency
range and provides three balanced RF outputs with
minimal degradation in signal quality. The single-
package surface mount device amplifies the input
signals using highly linear, low noise amplification
stages, and couples the amplified signal to three
separate output paths to drive video tuner inputs.
Each of the output paths includes independent
Automatic Gain Control (AGC). The overall linearity
Figure 1: Functional Block Diagram
of each tuner path is maintained across a wide AGC
range, ensuring low distortion effects on each output
signal.
Requiring only a single +5 Volt supply, the active
splitter design is implemented using the
ANADIGICS GaAs MESFET process. The surface
mount packaging makes the device ideal for use in
today’s multiple-tuner set-top boxes for Cable TV.
