1. A method for wireless communication at a wireless device, comprising:
applying a first set of digital pre-distortion coefficients to a plurality of antenna elements to form a first transmit beam that is associated with a first loading configuration of the plurality of antenna elements;
determining to switch from using the first transmit beam to using a second transmit beam that is different from the first transmit beam, the second transmit beam associated with a second loading configuration that is different from the first loading configuration;
applying a second set of digital pre-distortion coefficients to the plurality of antenna elements 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
transmitting a signal using the second transmit beam based at least in part on applying the second set of digital pre-distortion coefficients.
