Abstract: Certain aspects of the present disclosure generally relate to electronic components and, more particularly, to radio frequency front-end (RFFE) circuitry. One example apparatus may include a controller configured to: determine a first calibration point and a second calibration point for an amplifier, wherein the first calibration point is associated with a first supply voltage for the amplifier, and wherein the second calibration point is associated with a second supply voltage for the amplifier; and determine an operating point for the amplifier by interpolating based on the first calibration point and the second calibration point, the operating point being associated with a third supply voltage. The apparatus may also include an interface configured to control a power supply to provide the third supply voltage associated with the operating point for the amplifier.

Abstract: Certain aspects of the present disclosure provide techniques for identifying a minimal, or at least reduced, set of representative calibration paths in radio frequency (RF) circuits and calibrating other calibration paths based on calibration codes used for the representative calibration paths. An example method generally includes receiving a calibration data set including measurements associated with each calibration path of a plurality of calibration paths in an RF circuit. Based on a clustering model and the calibration data set, a plurality of calibration clusters is generated. From each respective calibration cluster of the plurality of calibration clusters, a respective representative calibration path for is selected for the respective calibration cluster. Generally, calibration codes generated for the representative calibration path are applicable to other calibration paths in the calibration cluster. A lookup table is generated associating a respective calibration path with other calibration paths in each respective calibration cluster.
