2.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 spe-
cific performance limits. For guaranteed specifications and test conditions, see the Electrical Charac-
teristics. The guaranteed specifications apply only to the test conditions listed.
3.MSL 2 (Moisture Sensitivity Level) is valid when the standard reflow process (235°C) is used. MSL 2
means 1 year shelf life after opening dry-pack. MSL 2(1 year shelf life) is also valid when the leadfree
reflow process (260°C) is used. Storage conditions are max. 30°C / 60% rel. humidity.
4.ESD STATEMENT
This device is a high performance RF integrated circuit and is ESD sensitive. Handling and assembly
of this device should be performed at ESD free workstations.
