Abstract
An embodiment electronic device comprises at least two antennas for transmitting signals, and at least one transmission path, the transmission path including a first coupling stage including a power divider, variable-gain power amplifiers, and a second coupling stage including a power combiner. Each coupling stage includes two inputs and two outputs, the two inputs of the first coupling stage being configured to receive a power input signal. Each output of the first coupling stage is connected to a different input of the second coupling stage via the variable-gain power amplifiers, and each output of the second coupling stage is connected to a different antenna. A controller is configured to control the gains of the variable-gain power amplifiers according to the characteristics of the power input signal, the signals transmitted by the antennas, and the coupling stages.
