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.
