Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
450MHz, 900MHz and 3500MHz performance measured with
external LO and RF matching. See Figure 1 and Applications Information.
Note 3:
Specifications over the –40
°
C to 85
°
C temperature range are
assured by design, characterization and correlation with statistical process
controls.
Note 4:
SSB Noise Figure measurements performed with a small-signal
noise source and bandpass filter on RF input, and no other RF signal
applied.
