1 RFIN/V
GG
1 RF Input/Gate Bias for Alternate Circuit for the Input Stage. This is a multifunction pin where the V
GG
1 function is
used in the alternate circuit only for biasing (see Figure 23 and Figure 25 for the alternate applications circuit and
alternate assembly drawings, respectively). This pin is dc-coupled and requires a dc block. See Figure 3 for the
interface schematic.

3 RFOUT/V
DD
RF Output/DC Bias for Alternate Application Circuit for the Output Stage. This is a multifunction pin where the V
DD
function is used in the alternate application circuit only for biasing (see Figure 23 and Figure 25 for the alternate
applications circuit and alternate assembly diagram, respectively). This pin is dc-coupled and requires a dc block.
See Figure 5 for the interface schematic.

Supply Voltage for Application Circuit. See Figure 22 and Figure 24 for the external components. See Figure 6 for
the interface schematic.
GND Die Bottom (Ground). The die bottom must be connected to RF/dc ground. See Figure 7 for the interface schematic.
