Description
Power control pin. This also provides power down when V
PC
is less
than +0.5V. Full power is achieved at 2.5V, and >45dB of gain control is
obtainable over the full range. Approximately 15mA current is drawn
into this pin at full power.
Interface Schematic
2
GND
Ground connection. This pin should be connected to the ground plane
through a short path and may be combined with the ground plane from
Pins 3, 6, 7, 10, 11, 14, and 15. All four of these wide leads are tied
together internally to provide a low-inductance and low thermal resis-
tance path to external ground. Ground vias should be placed as close
as possible to each ground lead.
Same as pin 2.

GND
VCC1
Power supply pin for the first stage. Also provides tuning for interstage
match.
5
RF IN
RF input. This input is DC coupled, so an external blocking capacitor is
required if this pin is connected to a DC path.
Same as pin 2.
See pin 4 schematic.

RF output pin. Bias is also fed to the final stage through this wide lead.
External matching is most easily achieved with a series transmission
line and shunt capacitors, as shown in the application schematic.
