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: External component values on the final test circuit shown in

Figure 2 are optimized for operation in the 2.4GHz to 2.5GHz band.

Note 3: Specifications over the –40

°C to 85°C temperature range are

assured by design, characterization and correlation with statistical process

controls.
