Description
Power supply for the driver stage, and interstage matching. Shunt
inductance is required on this pin, which can be achieved by an induc-
tor to V
the inductor is frequency dependent; 3.3nH is required for 830MHz,
and 1.2nH for 950MHz. Instead of an inductor, a high impedance
microstrip line can be used.
Not Connected.
RF input. This is a 50Ω 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. Keep traces physically short and connect immedi-
ately to the ground plane for best performance.
Same as pin 4.
Ground for stage 1. Keep traces physically short and connect immedi-
ately to ground plane for best performance. This ground should be iso-
lated from the batwing and other ground contacts. See evaluation
board layout.
Same as pin 6.
Power Control. When this pin is "low", all circuits are shut off. A "low" is
typically 0.5V or less at room temperature. During normal operation
this pin is the power control. Control range varies from about 2V for
0dBm to V
can be achieved depends on the actual output matching. PC should
never exceed 5.0V or V
Same as pin 4.
RF Output and power supply for the output stage. The four output pins
are combined, and bias voltage for the final stage is provided through
these pins. The external path must be kept symmetric until combined to
ensure stability. An external matching network is required to provide the
optimum load impedance; see the application schematics for details.
