AC ELECTRICAL CHARACTERISTICS
(MAX19790 Evaluation Kit, line and connector losses included, two attenuators in cascade, V
CC
= 4.75V to 5.25V, RF ports are
driven from 50I sources, input P
RF
= -10dBm, f
RF
= 950MHz to 2150MHz, V
CTRL
= +1.0V, T
C
= -40癈 to +85癈. Typical values are
for T
C
= +25癈, V
CC
= +5.0V, input P
RF
= -10dBm, f
RF
= 1500MHz, V
CTRL
= +1.0V, unless otherwise noted.)
Note 5: Operating outside this range for extended periods may affect device reliability. Limit pin input current to 40mA when V
CC
is not present (see Table 1 for R4 value).
Note 6: Operation outside this range is possible, but with degraded performance of some parameters. See the Typical Operating
Characteristics.
Note 7: f
1
= 1500MHz, f
2
= 1501MHz, -10dBm/tone at attenuator input.
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.
