Abstract:
1. Bidirectional signal mixer adapted to operate according to two modes, a reception mode, combining a radioelectric signal S an emission mode, combining a signal S four mixing cells, each being adapted to combine two signals to produce an output signal converted in frequencies with respect to the first of the two signals, a first phase shifting means adapted to dispatch the signal S a second phase shifting means adapted, in the reception mode, to dispatch the power of the signal S a third phase shifting means adapted, in the reception mode, to combine the signals from said mixing cells to produce a signal S the third shifting means being also adapted, in the emission mode, to dispatch the power of the signal S FI on each mixing cell and the second phase shifting means being also adapted, in the emission mode, to combine the signals from the said mixing cells to produce a radioelectric signal S RF free from the frequency component F OL , the combined signals comprising frequency components F OL in opposite phase and frequency components RF in phase.
