Summary:PROBLEM TO BE SOLVED: To provide an electronic interface between an NMR receiving resonator (RO) and a preamplifier.SOLUTION: An electronic interface 10 between a pure NMR resonator (RO) and a preamplifier is designed so as to convert the impedance of the NMR receiving resonator to the preamplifier in a receiving process and to open-circuit or detune the resonator in a transmission process and includes one or more switching diodes Dinto which a current is allowed to flow in the transmission process to open-circuit or detune the resonator. The electronic interface includes one or more control diodes D, Dcapable of supplying a current designed so as to flow through the switching diodes to the switching diodes. The control diodes are directly connected to the switching diodes or connected to the switching diodes through one or more additional series impedances.
