1. A resonator circuit configured to operate in a cryogenic environment of a magnetic resonance system, the resonator circuit comprising:
a first switch device configured to receive a magnetic resonance control signal;
a resonator device comprising a resonator, the resonator device configured to receive the magnetic resonance control signal from the first switch device and generate an electromagnetic field in a sample region of the magnetic resonance system in response to the magnetic resonance control signal;
a low-noise amplifier (LNA) device coupled between the resonator device and a receiver circuit of the magnetic resonance system; and
a second switch device coupled between the resonator device and the LNA device.
