Notes:
1TAMBIENT=22°C unless otherwise noted; exceeding any one of these absolute max-
imum ratings may cause permanent damage to the device.
2Operating at absolute maximum VD continuously is not recommended. If operation
at 10V is considered then IDS must be reduced in order to keep the part within
its thermal power dissipation limits. Therefore VGS is restricted to <-0.5V.
3Total Power Dissipation to be de-rated as follows above 22°C: PTOT=3.4-
(0.022W/°C)xTHS, where THS=heatsink or ambient temperature above 22°C.
Example: For a 85°C carrier temperature: PTOT=3.4-(0.022x(85-22))=2.01W
4Total Power Dissipation (PTOT) defined as (PDC+PIN)–POUT, where PDC: DC Bias
Power, PIN: RF Input Power, POUT: RF Output Power.
5Users should avoid exceeding 80% of 2 or more Limits simultaneously.
6Thermal Resistivity specification assumes a Au/Sn eutectic die attach onto an Au-
plated copper heatsink or rib.

Caution! ESD sensitive device.
Exceeding any one or a combination of the Absolute Maximum Rating conditions may
cause permanent damage to the device. Extended application of Absolute Maximum
Rating conditions to the device may reduce device reliability. Specified typical perfor-
mance or functional operation of the device under Absolute Maximum Rating condi-
tions is not implied.
