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.
Note 2: This device is a high performance RF integrated circuit and is ESD
sensitive. Handling and assembly of this device should on be done on ESD
protected workstations.
