ELECTRICAL CHARACTERISTICS
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
External components on the final test circuit are optimized for
operation at f

= 1730MHz and f
IF
= 170MHz (Figure 2).
Note 3:
Specifications over the –40
°
C to 85
°
C temperature range are
assured by design, characterization and correlation with statistical process
controls.
