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.

CPC classification number: H05K1/025 , H04B1/16 , H05K1/181 , H05K2201/09272 , H05K2201/09281 , H05K2201/10045 , H05K2201/10098
Abstract: A device includes a printed circuit board substrate, an antenna connected to the printed circuit board substrate, an amplifier connected to the printed circuit board substrate, and a matching track having a first end electrically connected to an input of the amplifier and a second end electrically connected to an output of the antenna. The matching track has an outgrowth that is symmetrical along a median axis of the outgrowth. The matching track is rectilinear and has a constant width over an initial part extending between the widening area and the first end. A median axis of the initial part and the median axis of the outgrowth form an angle comprised between 60 and 120°.
