Description
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
Same as pin 1.

Not connected.
RF input. This input is DC coupled, so an external blocking capacitor is
required if this pin is connected to a DC path.
Not connected.
See pin 1.

Power control pin. For maximum power this pin should be 3.3V. A
higher voltage is not recommended. For less output power and reduced
idle current this voltage may be reduced.

GND
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance.
Not internally connected.

NC
RF OUT
RF output and bias for the output stage. The power supply for the out-
put transistor needs to be supplied to this pin. This can be done
through a quarter-wave length microstrip line that is RF grounded at the
other end, or through an RF inductor that supports the required DC cur-
rents.

Not connected.
Power supply pin for the bias circuits. External low frequency bypass
capacitors should be connected if no other low frequency decoupling is
nearby.
Bias supply pin for the first stage. A small tuning capacitor is required to
set the desired frequency response. External low frequency bypass
capacitors should be connected as shown in the application schematic
if no other low frequency decoupling is nearby.
See pin 5.

Ground connection. The backside of the package should be connected
to the ground plane through a short path, i.e., vias under the device
may be required.
