Circuit for supplying power to a coil and NMR spectrometer comprising such a circuit

摘要

The circuit has two line portions (3, 3`), each with two conductors (5, 5`), where the conductors are coupled to a coil (2) at one of their ends. Other ends of the conductors are coupled to one another by a connecting component (6) to form an oscillating circuit (4). The circuit (4) has a symmetrical structure and is supplied through intermediate energy transfer by magnetic coupling of the supply circuit with the conductors. Independent claims are also included for the following: (A) a nuclear magnetic resonance probe including a multi-frequency supply circuit (B) a nuclear magnetic resonance spectrometer including a multi-frequency supply circuit.
