Abstract | The invention relates to a wireless communication terminal able to transmit and/or receive video, audio or data signals in a first and a second frequency band comprising a first MIMO circuit (1) of N paths (N ‰¥ 1) operating in the first frequency band and a second MIMO circuit (2) of M paths (M ‰¥ 1) operating in the second frequency band, the first and second MIMO circuits each being coupled to front-end modules (10, 20) comprising respectively N and M power amplifiers, the front-end modules being connected to an antenna system. It comprises a command circuit (4) connected at input to the first and second MIMO circuits to receive and process control data, the command circuit output controlling M (if M < N) or N (if N < M) switching circuits for which the inputs are connected to one of the M paths of the second MIMO circuit and for which an output is connected to one of the M power amplifiers, the other output being connected to one of the N power amplifiers via a summation circuit for which the other input is connected to one of the N paths of the MIMO circuit. |
