The invention concerns a transmission-reception head of a high frequency signal in the form of an integrated circuit comprising a transmission amplifier (23) and a reception amplifier (22). The transmission amplifier transmission terminals and the reception amplifier reception terminals are interconnected in a common transmission-reception terminal (20). The head comprises means for selecting one of the amplifiers and means for placing the other amplifier in a state of high impedance, relative to the transmission-reception terminal. |
