Description
This pin is internally not connected.
Interface Schematic
Ground connection. Keep traces physically short and connect immediately
to ground plane for best performance. Each ground pin should have a via
to the ground plane.

RF IN
RF input pin. This pin is NOT internally DC blocked. A DC blocking capacitor,
suitable for the frequency of operation, should be used in most applica-
tions. DC coupling of the input is not allowed, because this will override the
internal feedback loop and cause temperature instability.
This pin is internally not connected.

RF output and bias pin. Because DC is present on this pin, a DC blocking
capacitor, suitable for the frequency of operation, should be used in most
applications. For biasing, an RF choke in series with a resistor is needed.
The DC voltage on this pin is typically 8.3V with a current of 150mA (for
75Ω board). See device voltage versus device current plot. In lower power
