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 73.
2. Guaranteed by qualification. Qualification test conditions are listed in the "Production Test Conditions" section
on page 73.
3. Output power is dependent on matching components, board layout, and is measured at the pin.
