Note 5: Operation outside this range is possible, but with degraded performance of some parameters. See the Typical Operating
Characteristics.
Note 6: All limits include external component losses. Output measurements are performed at the RF output port of the Typical
Application Circuit.
Note 7: It is advisable not to continuously operate RF input 1 or RF input 2 above +15dBm.
