RF OUT
Same as pin 10.
2F0
Connection for the second harmonic trap. This pin is internally con-
nected to the RF OUT pins. The bonding wire together with an external
capacitor form a series resonator that should be tuned to the second
harmonic frequency in order to increase efficiency and reduce spurious
outputs.
VCC2
Same as pin 15.

Description
Ground connection for the driver stage. Keep traces physically short
and connect immediately to the ground plane for best performance. It is
important for stability that this pin has it’s own vias to the groundplane,
to minimize any common inductance. This pin is internally connected to
the ground slug.
Control input for the PIN diode. The purpose of the PIN diode is to
attenuate the RF input drive level when the V
APC
is low. This serves
both to reduce the leakage through the device cause by self biasing
when driving with high level at the RF input, as well as to maintain a
good input match when the bias of the input stage is turned off. When
this pin is “high” the PIN diode control is turned on. See the Theory of
Operation for more details.
RF Input. This is a 50
input, but the actual impedance depends on the
interstage matching network connected to pin 5. An external DC block-
ing capacitor is required if this port is connected to a DC path to ground
or a DC voltage.

GND1
Ground connection for the pre-amplifier stage. Keep traces physically
short and connect immediately to the ground plane for best perfor-
mance. It is important for stability that this pin has it’s own vias to the
groundplane, to minimize any common inductance.
Power supply for the pre-amplifier stage and interstage matching. This
pin forms the shunt inductance needed for proper tuning of the inter-
stage match. Please refer to the application schematic for proper con-
figuration, and note that position and value of the components are
important.
Power Control for the driver stage and pre-amplifier. When this pin is
"low," all circuits are shut off. A "low" is typically 0.5V or less at room
temperature. A shunt bypass capacitor is required. During normal oper-
ation this pin is the power control. Control range varies from about 1.0V
for -10dBm to 2.6V for +33dBm RF output power. The maximum power
that can be achieved depends on the actual output matching; see the
application information for more details. The maximum current into this
pin is 5mA when V
APC1
=2.6V, and 0mA when V
APC
=0V.

Not connected. Connect this pin to the ground plane for compatibility
with future packages.
RF Output and power supply for the output stage. Bias voltage for the
final stage is provided through this wide output pin. An external match-
ing network is required to provide the optimum load impedance.
