See Note 2.
Note 1: All specification and characterization data has been gathered on standard FR-4 evaluation boards. These evaluation boards are not
optimized for frequencies above 2.5GHz. Performance above 2.5GHz may improve if a high performance PCB is used.
Note 2: The RF3398 must be operated at or below 60mA in order to achieve the thermal performance listed above. While the RF3398 may be
operated at higher bias currents, 40mA is the recommended bias to ensure the highest possible reliability and electrical performance.
Note 3: Because of process variations from part to part, the current resulting from a fixed bias voltage will vary. As a result, caution should be
used in designing fixed voltage bias circuits to ensure the worst case bias current does not exceed 60mA over all intended operating condi-
tions.
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.
