Recommended Operating
Conditions
Note 2: 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 3: This device is a high performance RF integrated circuit with an ESD
rating
should be done at ESD protected workstations.
Note 4: GND = 0 V.
