Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The performance is measured with the test circuit shown in
Figure 1. For 900MHz measurements, C1 = 3.9pF. For all other
measurements, C1 is not used.
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: Operation over a wider frequency range is possible with reduced
performance. Consult the factory for information and assistance.
Note 5: Turn-on and turn-off times correspond to a change in the output
level of 40dB.
Note 6: The part is operable below 3.6V with reduced performance.
