Note 1: Absolute Maximum Ratings indicate limits beyond which damage to
the device may occur. Recommended Operating Conditions indicate condi-
tions for which the device is intended to be functional, but do not guarantee
specific performance limits. For guaranteed specifications and test condi-
tions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed.
Note 2: This device is a high performance RF integrated circuit with an ESD
rating <2 kV and is ESD sensitive. Handling and assembly of this device
should only be done at ESD protected work stations.
