Note 1: Absolute Maximum Ratings are those values beyond which the
life of a device may be impaired.
Note 2: Tests are performed as shown in the configuration of Figure 5.
Note 3: Specifications over the –40°C to 85°C temperature range are
guaranteed by design, characterization and correlation with statistical
process controls.

Note 4: The Linear Dynamic Range is defined as the range over which the
output slope is at least 50% of the average slope from –50dBm to –20dBm.
Note 5: The output voltage is settled to the full specification within 1dB.
Note 6: Refer to Figure 1 and Applications Information.
