Abstract:
1. A communications device comprising: an antenna port configured for coupling to any given one of multiple different antennas; transmitter circuitry configured to broadcast a radio frequency (RF) output signal across any given one of the multiple different antennas that is coupled to the antenna port at a first frequency; stored antenna compensation information corresponding to each given one of the multiple different antennas that indicates an amount of amplitude compensation to apply depending on which given one of the multiple antennas is coupled to the antenna port in order to adjust the corresponding amplitude level at which the RF output signal is broadcast at the first frequency across a given one of the multiple antennas when it is coupled to the antenna port, the amplitude compensation indicated by the stored antenna compensation information being different at the first frequency for each of the multiple different antennas; and a controller configured to adjust an amplitude level at which the RF output signal is broadcast at the first frequency across a first one of the multiple antennas when it is coupled to the antenna port by the amount indicated by the stored antenna compensation information corresponding to the first antenna for the first frequency so as to set the amplitude of the RF output signal to a first amplitude level at which the RF output signal is broadcast at the first frequency across the first antenna coupled to the antenna port, based on the antenna compensation information; wherein the antenna compensation information is configured to compensate for properties of each given one of the multiple antennas when it is coupled to the antenna port while the RF output signal is being broadcast at the first frequency, and wherein the antenna port, the transmitter circuitry, and the controller are at least partially integrated on the same integrated circuit.
