RF output and bias pin. Bias should be supplied to this pin through an external series resistor
and RF choke inductor. Because DC biasing is present on this pin, a DC blocking capacitor
should be used in most applications (see application schematic). The supply side of the bias
network should be well bypassed.

Exposed area on the bottom side of the package must be soldered to the ground plane of the
board for optimum thermal and RF performance. Several vias should be located under the
EPAD as shown in the recommended land pattern on page 5.
