It is recommended to follow the flowcharts described in
any calibration, as they require a precise set of sequential operations. The further
comments can only give an overview of what is typically done during the flowchart.
The TDA18211HD has two calibration modes: one for the image rejection calibration, and
one for the RF tracking filters calibration.
