Abstract
An amplifier device (14) is adapted for an antenna-like transducer for MRI applications, especially for an RF coil. The amplifier device (14) includes at least one amplifier channel (16) including: an input connection device (18) for connecting an RF signal source (12); an output connection device (20) for connecting the antenna-like RF transducer; an RF amplifier unit (22); and an impedance matching circuit (24) configured to adapt the coupling of the RF amplifier unit (22) to the actually connected antenna-like RF transducer with regard to an actual load of the amplifier device (14). The load results from the combination of the antenna-like RF transducer and a person or sample interacting with the antenna-like RF transducer. The impedance matching circuit (24) establishes an electric line (34) between the RF amplifier unit (22) and the antenna-like transducer with an adjustable line length.
