Abstract: An antenna controller for an antenna is configured to request and receive status information comprising power amplifier data of at least two adjustable power amplifiers. The antenna controller is configured to determine at least one target setting for the at least two adjustable power amplifiers based on the received power amplifier data, and to send the at least one target setting for the at least two adjustable power amplifiers. Hereby it is made possible for an antenna controller to set an overall target for multiple adjustable power amplifiers of the antenna. This in turn makes it possible to make the settings for the adjustable power amplifiers such that the transmission signal becomes linearized by a shared digital pre-distorter when transmitting using the multiple adjustable power amplifiers of the antenna. A Radio Frequency Integrated Circuit controller for an antenna subarray is configured to control at least one adjustable power amplifier.
