Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: 450MHz and 900MHz performance measured with external LO and
RF matching. 2600MHz and 3600MHz performance measured with
external 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.
