Abstract: A transmitter/receiver device include an antenna, a voltage source, a radio frequency receiver connected to the antenna and powered by the voltage source, a radio frequency transmitter connected to the antenna and powered by the voltage source, and a switch coupled to the antenna, the receiver and the transmitter and configured to couple/decouple the antenna from the transmitter or from the receiver. The antenna is shared between the transmitter and the receiver. The receiver includes a radio frequency stage that includes an amplifier device having an input coupled to the antenna. The amplifier device includes an amplifier switch configured to connect or disconnect the amplifier device from the voltage source.
