Notes:
1.  All specification guaranteed by production test unless otherwise noted. Production test conditions and max limits are 
listed in the "Production Test Conditions" section on page 14.
2. Guaranteed by qualification. Qualification test conditions are listed in the "Production Test Conditions" section on 
page 14.
3. Output power is dependent on matching components, board layout, and is measured at the pin.
