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. The voltage at all the power supply pins of VddRF1, VddRF2,
VddRF3, VddRF4, VddRF5, VddIF1 and VddIF2 must be the same. V
CC
will be used to refer to the voltage at these pins and I
CC
will be used to refer to the sum
of all currents through all these power 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.
