NOTES

1. NIC = NOT INTERNALLY CONNECTED. THESE PINS ARE NOT CONNECTED INTERNALLY.

HOWEVER, ALL DATA SHOWN HEREIN WAS MEASURED WITH THESE CONNECTED

TO RF AND DC GROUND.

2. EXPOSED PAD. THE EXPOSED PAD MUST BE CONNECTED TO RF AND DC GROUND.

NIC

Not Internally Connected. These pins are not connected internally. All data shown is

measured with these pins connected to the RF and dc ground.

2, 4, 15, and 17

GND

Ground. These pins must be connected to the radio frequency (RF) and dc ground.
