1. An apparatus for wireless communication at a wireless device, comprising:
a processor;
memory coupled with the processor; and
instructions stored in the memory and executable by the processor to cause the apparatus to:
apply a first set of digital pre-distortion coefficients to a first plurality of antenna elements to form a first transmit beam that is associated with a first loading configuration of the first plurality of antenna elements;
determine to switch from using the first transmit beam to using a second transmit beam, the second transmit beam associated with a second loading configuration of a second plurality of antenna elements that is different from the first loading configuration of the first plurality of antenna elements;
apply a second set of digital pre-distortion coefficients to the first plurality of antenna elements, the second plurality of antenna elements, or both to form the second transmit beam, wherein the second set of digital pre-distortion coefficients is different from the first set of digital pre-distortion coefficients; and
transmit a signal using the second transmit beam based at least in part on applying the second set of digital pre-distortion coefficients.
