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.
