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 conditions.
Caution! ESD sensitive device.
