Description
Backside paddle. Multiple vias should be employed to
minimize inductance and thermal resistance; see ‘PCB
Mounting Pattern’ on page 12 for suggested footprint
No internal connection; Recommend grounding these pins
for best RF performance. See ‘PCB Mounting Pattern’ on
page 12 for suggested footprint
