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.

Abstract: In an embodiment method, a hybrid coupler comprises a first input receiving an analog signal, a second input receiving an additional analog signal phase shifted by 90° from the analog signal, and first and second outputs. The method comprises injecting into the second output a test signal having an initial test phase, iteratively generating a current test phase for the test signal, from the initial test phase to a final test phase equal to the initial test phase increased by at least one portion of one complete revolution, and, in each iteration, measuring the current peak value of the first output, and storing the current test phase and the current peak value as a maximum/minimum peak value if there is not a stored maximum/minimum peak value higher/lower than the current peak value, respectively, and determining a phase of the analog signal from the stored test phase.

Abstract: In an embodiment, a method for determining the phase shift between a first signal and a second signal includes: delivering the first signal to a first input of a 90° hybrid coupler; delivering the second signal to a second input of the 90° hybrid coupler; determining a first piece of information relating to a power of a first output signal delivered to a first output of the 90° hybrid coupler; determining a second piece of information relating to a power of a second output signal delivered to a second output of the coupler; and adjusting the phase of the second signal until obtaining a calibrated phase for which the first piece of information is substantially equal to the second piece of information, wherein the first and second signals have identical frequencies, and wherein the phase shift between the first signal and the second signal is equal to the calibrated phase.
