Abstract
An electronic interface () between a pure NMR receiver resonator (RO) and a preamplifier is characterized in that one or more control diodes (D, D) are provided by means of which the current designed to flow through the switching diodes can be fed into these switching diodes, and the control diodes are connected to the switching diodes directly or via one or more additional series impedances. In this fashion, the impedance of the resonator is transformed to the required preamplifier or line impedance during the receiving process with little loss. In particular, during the receiving process, matching can be adjusted during the transmitting process, the current in the inductance of the resonator generated by the Bfield of the transmitting resonator is minimized and all components are protected against damage.
