Note 1:
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. "Recommended Operating Conditions" indicate conditions for
which the device 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 conditions listed. Note also that these maximum ratings imply that the voltage at all the power
supply pins of VccRF, VccIF, VddRF, and VddIF are the same. V
CC
will be used to refer to the voltage at these pins.
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-free workstations.
