Description
Power supply for the driver stage, and interstage matching. Shunt
capacitance is required on this pin. The value of the capacitance is fre-
quency dependent. 4.7pF centers the gain at 1880 MHz.
Interface Schematic

GND
Ground connection for final stage. Keep traces physically short and
connect immediately to the ground plane for best performance.
Same as pin 2.

GND
RF IN
RF input. This is a 50
input, but the actual input impedance depends
on the interstage matching network connected to pin 1. An external DC
blocking capacitor is required if this port is connected to a DC path to
ground or a DC voltage.
Ground connection for the driver stage. Keep traces physically short
and connect immediately to the ground plane for best performance.
Same as pin 2.

Bypass Pin. Part of the matching circuit for interstage match. DC con-
nected to VCC1. Use a suitable bypass capacitor to ground. Keep
capacitor as close to pin as possible.
Power Control. When this pin is "low", all circuits are shut off. A "low" is
typically 0.5V. When this pin is "high", the part operates normally, and
the pin consumes approximately 13mA during normal operation.
This pin should never exceed 5V.

RF Output and power supply for the output stage. The two output pins
are combined, and bias voltage for the final stage is provided through
these pins. An external matching network is required to provide the
optimum load impedance; see the application schematics for details.
