Operating Ratings 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 2: This Device is a high performance RF integrated circuit with an ESD rating < 2kV and is ESD sensitive. Handling and assembly of this device should only be done at ESD-free workstations. Electrical Characteristics (V ccRF=VccIF=VPRF=VPIF= 3.0V; −40˚C < TA< +85˚C except as specified) All min/max specifications are guaranteed by design, or test, or statistical methods.
