Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage

to the device may occur. Operating Ratings indicate conditions for which the

device is intended to be functional, but do not guarantee specific perfor-

mance 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

should only be done at ESD-free workstations.
