Description
This pin is internally not connected.
Ground connection. Keep traces physically short and connect immedi-
ately to ground plane for best performance. Each ground pin should
have a via to the ground plane.
Same as pin 2.
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 applications. DC coupling of the input is not allowed, because this
will override the internal feedback loop and cause temperature instabil-
ity.
This pin is internally not connected.

RF output and bias pin. Because DC is present on this pin, a DC block-
ing 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. See device voltage versus device current plot. In lower power
applications the value of R
