Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The 900MHz and 1900MHz performance is measured with the test

circuit shown in Figure 1. The 350MHz performance is measured using the

test circuit in Figure 2.

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 by 40dB.
