Claim:
1. An electronic interface between an NMR receiver resonator and at least one preamplifier, the NMR receiver resonator being designed as a receive-only resonator for receiving NMR signals emitted from a sample in response to irradiation of that sample with radio frequency radiation generated by a separate transmitter during a transmitting process, the electronic interface comprising: at least one switching diode, said at least one switching diode being disposed, structured and dimensioned to open or detune the NMR receiver resonator during the transmitting process; and at least one control diode, said control diode being structured to facilitate feeding of current through said control diode and into said switching diode during the transmitting process, thereby opening or detuning the NMR receiver resonator, wherein said control diode is directly connected to said switching diode or is connected to said switching diode via at least one series impedance, the interface thereby being structured for transforming an impedance of the NMR receiver resonator to the preamplifier during a receiving process and for opening or detuning the NMR receiver resonator during the transmitting process.
