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 P2XLO = –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.
