FIELD: radio engineering, communication.
SUBSTANCE: device (10) comprises a radio frequency resonant circuit including a radio frequency reception antenna (15) for receiving MR signals, and a radio frequency amplifier (17) connected at its input to the radio frequency resonant circuit for amplifying the received MR signals. The invention provides a detection circuit (18) configured to derive a switching signal from an output signal of the radio frequency amplifier (17).
EFFECT: switching circuit responds to the switching signal, wherein the switching circuit is configured to switch the radio frequency resonant circuit between a resonant mode and a non-resonant mode.
