Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: Each set of frequency conditions requires an appropriate test board.
Note 3: Specifi cations 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: SSB Noise Figure measurements are performed with a small-
signal noise source and bandpass fi lter on the RF input (downmixer) or
output (upmixer), and no other RF input signal applied.
