GND
Ground: Backside of package has exposed metal ground slug that must
be connected to ground thru a short path. Vias under the device are
required.
3, 14 Vpd1, Vpd2
Power Control Pin. For maximum power, this pin should be connected
to 4.0V. For 5V operation, a dropping resistor is required. A higher
voltage is not recommended. For lower idle current, this voltage can be
reduced.
6 RFIN This pin is AC coupled and matched to 50 Ohms from 0.8 to 1.0 GHz.
11, 12 RFOUT RF output and bias for the output stage.
16 Vcc
Power supply voltage for the  rst ampli er stage. An external bypass
capacitor of 330 pF is required as shown in the application schematic.

Evaluation PCB
The circuit board used in the  nal application should
use RF circuit design techniques. Signal lines
should have 50 ohm impedance while the package
ground leads and exposed paddle should be con-
nected directly to the ground plane similar to that
shown. A sufficient number of via holes should be
used to connect the top and bottom ground planes.
The evaluation board should be mounted to an
appropriate heat sink. The evaluation circuit board
shown is available from Hittite upon request.
