RECOMMENDED SEQUENCE FOR ENABLING THE DPD TRACKING CALIBRATION

The sequence for running DPD tracking calibrations is shown in Table 14.
Table 14. DPD Tracking Calibration Bringup Sequence
Step Action
1 Program the device and run initial
calibrations(including TxQEC initial calibration) with
the PA turned off.
2 Setup external Tx to ORx mapping
3 Adjust ORx gain to an appropriate value to avoid
saturation. The default gain index in ADRV9025 is
255 (0dB attenuation)
4 Turn on the PA and run the external path delay initial
calibration. Alternatively, factory calibrated path
delay values can be programmed via
ExternalPathDelaySet() commands
5 Run the Tx external LO Leakage initial calibration
6 If using ADRV9025 CFR, configure the CFR settings.
7 If using ADRV9025 CFR, run the CFR initial
calibration
8 Load the DPD model
9 Assert DPD Reset
9b If a unique DPD model is required to be applied to each Model
10 Setup DPD mode of operation, DPD peak search
window size and low power threshold
11 Setup DPD fault conditions and recovery
actions(optional)
12 Setup CLGC configurations and target loop gain
13 Enable Tx QEC and Tx LO Leakage tracking
Calibrations
14 Enable DPD Tracking Calibration
15 Enable CLGC Tracking Calibration
16 Monitor DPD tracking calibration status
