AC ELECTRICAL CHARACTERISTICS
(MAX19790 Evaluation Kit, line and connector losses included, two attenuators in cascade, V
driven from 50I sources, input P
for T
Note 5: Operating outside this range for extended periods may affect device reliability. Limit pin input current to 40mA when V
Note 6: Operation outside this range is possible, but with degraded performance of some parameters. See the Typical Operating
Note 7: f
Note 8: Guaranteed by design and characterization.
Note 9: Switching time is measured from 50% of the control signal to when the RF output settles to Q1dB.
