Note 1: Absolute Maximum Ratings indicate limits beyond which damage to
the device may occur. Operating Conditions indicate conditions for which the
device is intended to be functional. For guaranteed specifications and test
conditions, 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 be done on ESD
protected workstations.
