Machine learning-based radio frequency circuit calibration

A method for calibrating a radio frequency (RF) circuit, comprising:

• generating calibration codes for a representative calibration path associated with a calibration cluster in an RF circuit;
• identifying, from a lookup table associating the representative calibration path with the calibration cluster, other calibration paths in the calibration cluster for which the generated calibration codes are applicable;
• and
• calibrating the other calibration paths in the calibration cluster based on the generated calibration codes for the representative calibration path.

A system, comprising:

• a memory having executable instructions stored thereon;
• and
• a processor configured to execute the executable instructions to cause the system to:
• receive a calibration data set including measurements associated with each calibration path of a plurality of calibration paths in an RF circuit;
• generate, based on a clustering model and the calibration data set, a plurality of calibration clusters;
• select, from each respective calibration cluster of the plurality of calibration clusters, a respective representative calibration path for the respective calibration cluster, wherein calibration codes generated for the respective representative calibration path are applicable to other calibration paths in the calibration cluster;
• and
• generate a lookup table associating, for each respective calibration cluster, the respective representative calibration path and the other calibration paths associated with the respective calibration cluster.
