Note 1: 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 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 protected work stations.

Note 3: GND=0V
