NIC

Not Internally Connected. The pins are not connected internally; however, all data shown herein was measured

with these pins connected to GND externally.

RFIN

RF Input. This pin is dc-coupled and ac matched to 50 Ω. An external dc blocking capacitor is required on this pin.

3

GND

Ground. This pin must be connected to ground.

5

RFOUT

RF Output. This pin is ac matched to 50 Ω and supplies dc bias for the output stage.

EPAD

Exposed Pad. The exposed pad must be connected to GND for proper operation.
