Hi Team,
When doing temperature compensation on AFE7769, we found that there was a problem with the attenuation accuracy of RX. When the attenuation was 1dB, 2dB, or 3 dB, the error was negligible. But when the attenuation was 5dB, the error was very noticeable, and the attenuation was actually only about 4.2dB.
What causes this?
Kind regards,
Katherine
