Patent ID: 7119543

Claim:
A generator device for generating a magnetic resonance excitation signal, comprising: an input element adapted to receive an input signal; a signal divider following said input element for dividing said input signal into at least two sub-signals; at least two amplification stages connected in parallel following said signal divider for respectively amplifying said sub-signals to produce respective amplified signals; a signal combiner connected following said amplification stages for combining said amplified signals to form an aggregate signal; an output element connected following said signal combiner for making said aggregate signal externally available as an output signal; an input sensor device connected between said input element and said signal divider for acquiring at least one reference signal corresponding to said input signal; at least two output sensor devices respectively connected between said amplification stages and said signal combiner for respectively acquiring actual signals respectively corresponding to said amplified signals; and a control device connected to said input sensor device, said output sensor devices, and at least one of said amplification stages, for controlling said at least one of said amplification stages dependent on the reference signal and the actual signals from the output sensor devices, for causing said amplified signals to exhibit a predetermined amplitude ratio and a predetermined phase relation relative to each other.
