Table 6. Absolute Amplitude Accuracy (Continued)
Center Frequency
Absolute Amplitude Accuracy,
Temperature 23 °C ± 5 °C (dB)
>3 GHz to 3.9 GHz
1.3
>3.9 GHz to 4.4 GHz
1.5
Note
Absolute amplitude accuracy uses a correction coefficient in EEPROM to
improve performance. Performance is verified over the first 45 dB of RX
attenuation.
Note
Correction coefficients in EEPROM are valid only when the baseband
amplifier is in the signal path.

Note
Performance is measured with an input reference level of -48 dBm and
with 0 dB of RX attenuation.
