A combiner/splitter device ( 100 ) comprises two transmission lines ( 23, 24 ), wound to form a helical coil ( 55 ), this helical coil being bent to a toroidal shape. Furthermore, a capacitor ( 51 ) is provided, connected in parallel with the two outer conductors ( 25, 26 ) of the two transmission lines ( 23, 24 ). The combination of the wound transmission lines and said capacitor forms a parallel resonator ( 56 ). The combiner/splitter device is suitable for use in a magnetic resonance imaging (MRI) system to combine the output signals of a receiver coil system and/or to split the input signal of a transmission coil system used in the MRI system.
