摘要
The invention provides for a system (200) for generation of a radio frequency, RF, excitation signal for excitation of nuclei via an RF excitation coil (114) in a magnetic resonance system (100). The system comprises power generation units (203-206) each comprising a synthesizer (211-214), an RF amplifier (231-234), and a first feedback loop (251-254) unit adapted to configure the synthesizer to generate an RF signal which after amplification by the RF amplifier has a predefined first signal characteristic and a combiner (261) adapted for combining the RF signals amplified by the RF amplifiers for obtaining the RF excitation signal.
