Note 1: Absolute Maximum Ratings are those values beyond which the life of
the device may be impaired.
Note 2: LO Absolute Maximum Ratings apply for each LO pin separately.
Note 3: Component values listed in Figure 3 for 1.8GHz evaluation board were
used to guarantee 1.8GHz performance.

Note 4: Specifications over the –40°C to 85°C operating temperature range
are assured by design, characterization and correlation with statistical process
controls.
Note 5: When EN ≤ 0.3V, enable current is <10µA.
Note 6: When GS ≤ 0.3V, gain select current is <10µA.
