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, refer to the Electrical Characteristics section. The guaranteed specifi-
cations apply only for the 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.
