Description
Power supply for the driver stage and interstage matching. Matching is
typically done by a microstrip line to V
CC
that is RF grounded at the
V
CC
side. See the application information for details.
Ground connection for the driver stage. Keep traces physically short
and connect immediately to the ground plane for best performance.
This connection should be separated from the ground connection for
the output stage, i.e., using separate traces and vias.
Power Down control. When this pin is "low", all circuits are shut off. A
"low" is typically 1.2V or less at room temperature. When this pin is
"high", all circuits are operating normally. A "high" is V
CC
. If V
PD
is
below V
CC
, output power and performance will be degraded. This could
be used to obtain some gain control, but results are not guaranteed.
RF Input. This is a 50
input, but the actual impedance depends on
the matching provided on pin 1. An external DC blocking capacitor is
required if this port is connected to a DC path to ground.
Ground connection for the output stage. Keep traces physically short
and connect immediately to the ground plane for best performance.
This connection should be separated from the ground connection for
the driver stage, i.e., using separate traces and vias.
RF Output and power supply for the output stage. Bias for the output
stage needs to be provided on this pin. This can be done through a
quarter-wave microstrip that is RF grounded on the other end. For
matching to 50
, an external series microstrip line is required.
Same as pin 6.

Power supply for the bias circuits. An external RF bypass capacitor of
22 pF is required. Keep the traces to the capacitor as short as possible,
and connect the capacitor immediately to the ground plane.
