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

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: Turn-On and Turn-Off times are based on the rise and fall times of

the RF output envelope from –40dBm to full power with an IF input power

of –10dBm.
