Note 2: Absolute Maximum Ratings indicate limits beyond which damage to
the device may occur. Operating Ratings indicate conditions for which the de-
vice is intended to be functional, but do not guarantee specific performance
limits. For guaranteed specifications and test conditions, see the Electrical
Characteristics. The guaranteed specifications apply only for the test condi-
tions listed.
Note 3: This device is a high performance RF integrated circuit and is ESD
sensitive. Handling and assembly of this device should only be done at ESD
free workstations.
Note 4: VCC is defined as VCC =VCC1=VCC2.
