Abstract
A device for generating wideband signals in a local coil and a magnetic resonance tomography system with the device are provided. The device has a first analog-digital converter for digitizing a magnetic resonance signal, a signal conditioner, a pulse filter, and a transmit antenna. The signal conditioner is configured to increase a harmonic component in an output signal of the first analog-digital converter, and the pulse filter is configured to restrict an output signal of the signal conditioner to a predetermined frequency band before the output signal of the signal conditioner is emitted via the transmit antenna. The receiver is configured to receive and digitize the signal via a receive antenna, and regain a digital representation of the magnetic resonance signal by a signal processor.
