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.
