Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
Tests are performed as shown in the configuration of Figure 2.
Note 3:
Specifications over the –40
°
C to 85
°
C temperature range are
assured by design, characterization and correlation with statistical process
control.
Note 4:
Measured at P
2XLO
= –10dBm and output frequency = 1MHz.
Note 5:
Turn ON and Turn OFF times are based on rise and fall times of the
output baseband voltage with RF input power of –10dBm.
