Abstract:
1. An active antenna array for transceiving signals from a base transceiver station, wherein the active antenna array comprises: a heat dissipating body; at least one first power amplifier in thermal contact with the heat dissipating body, wherein the first power amplifier amplifies a first input signal from the base transceiver station; at least one second power amplifier in thermal contact with the heat dissipating body, wherein the at least one second power amplifier amplifies a second input signal from the base transceiver station; wherein the at least one first power amplifier is adapted to operate in a first frequency band and the at least one second power amplifier is adapted to operate in a second frequency band; and a power level controller for adjusting relative power levels of a first output signal emanating from the at least one first power amplifier and a second output signal emanating from the at least one second power amplifier.
